DC Circuit Breakers: Safeguarding Electrical Systems with 12V DC Breaker Technology

Circuit breakers are essential components in electrical systems, serving as crucial safety measures to protect circuits and devices from overcurrents and potential damages. While AC circuit breakers have been widely used for decades, the rise of DC-powered applications has necessitated the development of specialized DC circuit breakers. In this article, we will explore the significance of DC circuit breakers, focusing on the technology behind 12V DC circuit breakers and their critical role in safeguarding electrical systems.

Understanding DC Circuit Breakers:

DC circuit breakers, also known as DC breakers, are devices designed to interrupt the flow of current in a direct current (DC) circuit when an abnormal condition arises. Similar to AC circuit breakers, their primary purpose is to prevent excessive current from damaging the circuit components and to ensure the safety of both equipment and personnel.

The key difference between AC and DC circuit breakers lies in the behavior of the current. In AC circuits, the current undergoes periodic reversals of direction, which aids in natural current interruption. In contrast, DC circuits maintain a steady flow of current in a single direction, making the interruption more challenging. Therefore, DC circuit breakers require different designs and mechanisms to handle the unique characteristics of direct current.

Technology of 12V DC Circuit Breakers:

The 12V DC circuit breakers are specifically engineered to handle low-voltage DC systems, commonly found in automotive, marine, and off-grid solar applications. The technology employed in these breakers is tailored to efficiently protect circuits operating at 12 volts, ensuring optimal safety and performance.

Bimetallic Strip or Magnetic Trip Mechanism:

To detect overcurrent conditions, 12V DC circuit breakers often employ either a bimetallic strip or magnetic trip mechanism. In both cases, when the current exceeds a predetermined threshold, the mechanism is triggered, causing the circuit breaker to trip and interrupt the current flow.

The bimetallic strip consists of two different metals bonded together, each with different thermal expansion coefficients. When current passes through the strip, it generates heat, causing it to bend and activate the trip mechanism.

The magnetic trip mechanism relies on the principle of magnetic induction. An electromagnet is connected to the circuit, and when the current exceeds the set value, the magnetic field generated trips the breaker.

Hybrid and Electronic DC Circuit Breakers:

With advancing technology, hybrid and electronic DC circuit breakers have emerged as more sophisticated alternatives. Hybrid breakers combine traditional thermal-magnetic protection with electronic components, providing faster response times and precise current monitoring. Electronic DC circuit breakers, on the other hand, use electronic sensors to monitor current and respond rapidly to overcurrent events, enhancing the overall efficiency and accuracy of protection.

Importance of 12V DC Circuit Breakers:

The increasing prevalence of 12V DC-powered applications, such as automobiles, boats, and off-grid energy systems, highlights the critical role of 12V DC circuit breakers. These breakers act as the first line of defense against potential electrical faults, ensuring the safe and reliable operation of equipment and systems.

In automotive applications, 12V DC circuit breakers safeguard vital components like headlights, wipers, and power windows. Similarly, in marine settings, they protect electrical systems on board from the harsh marine environment and fluctuations in electrical currents.

In off-grid solar installations, 12V DC circuit breakers are instrumental in safeguarding batteries, charge controllers, and other crucial components from damage caused by excessive currents. This protection is especially vital in remote locations where servicing and repairs may be challenging.

Conclusion:

In conclusion, 12V DC circuit breakers are indispensable components that play a crucial role in protecting electrical systems from overcurrent conditions. Through various mechanisms, including bimetallic strips, magnetic trips, and advanced electronic technologies, these circuit breakers ensure the safety, reliability, and efficiency of 12V DC-powered applications.

As technology continues to advance, the development of more sophisticated and responsive 12V DC circuit breakers will further enhance electrical system protection and contribute to the growth of various industries, from automotive and marine to renewable energy. By investing in high-quality and appropriate DC circuit breakers, individuals and businesses can ensure the smooth operation of their electrical systems and minimize the risk of costly damages or accidents.

Reading more about inrush current control techniques now, all I knew before this was that you use Negative Temperature Coefficient parts to control it without affecting overall efficiency too much.

I've never had to design a board that drew much power, or didn't just use an off the shelf power supply. Power supply design is black magic so even major companies usually just buy certified open frame units to avoid redoing a ton of regulatory work, it's what's best for everyone. All the appliances at First Job just had a 24V Great Wall open frame units jammed in there, plus consumer 12V supplies for the network gear.

You can do some clever things involving having the NTC take itself out of the loop with a relay and a zener diode if you have really high efficiency targets to hit or you don't want to fry your NTC as the current picks up. I love these kinds of self-contained feedback tricks, they're super handy. And of course there's digital current controllers for high precision applications.

Figure 5 shows the relay circuit for a 1kW power supply. The relay is initially turned off. During power up, the input current flows through a 10Ω/10W cement resistor. Once the power supply is energized, a regulated bias voltage, 12V2, turns on the relay to minimize the power dissipation on the current-limiting circuit during normal operation.

Anyway. Reading specs it looks like there's a systematically higher inrush current in computer PSU's when you connect them to 230V, which is probably just Ohm's Law at work. A lot of supplies with really good 110V inrush limiting have utterly dogshit 230V inrush limiting.

An interesting problem I realize this might cause is that, because most tech reviewers are Americans with 110V, they won't pick this up as often. E.g. the highly recommended SF750 from Corsair has fantastic 120V inrush of ~30A but on 230W it's almost 80A, which would definitely trip a lot of home breakers.

How to connect a solar panel ?

If you are interested in the topic of how to connect a solar panel, you should study the installation and device features well. It is also worth asking yourself the question - what is a home power plant for, and what is the main purpose of its installation. As practice shows, there are several answers here: the fight against constant power outages, energy savings and the ability to create a completely autonomous power grid. When the main goal is defined, then it is already possible to approach the technical side of the issue. The prepared article will tell you how to connect a solar battery from Energovolt and other Australia of such a system.

Different types of solar power plants ?

In order to understand the connection diagrams well, you need to familiarize yourself with the complete set of equipment for a small Energovolt solar system. It is worth clarifying that solar power plants are networked and autonomous, so their set of equipment is slightly different. For example, the network type of Solar Panel in Australia Energovolt is successfully used in shopping malls, offices, private houses, farms, hotels, and the list of components is as follows:

Solar panels of polycrystalline or monocrystalline type.

A single-core copper cable, always with high-quality double insulation and good resistance to the influence of a rather aggressive environment. The recommended cross section is 6 mm or more.

Switches of direct and alternating current.

Quick connectors for connecting panels.

DC SPD.

DOKA sensor.

Fasteners must be ordered separately.

A reversible electricity meter is necessary in cases where it is planned to sell electricity to the state. Autonomous solar power plants Energovolt is supplied in the following configuration:

solar panels of a certain type;

Battery charge controller;

The inverter is not included in every kit;

Several options for batteries (often gel);

Protection devices (fuses, circuit breakers);

Cables with a cross section of at least 4 mm.

Autonomous Energovolt kits are used in most cases for street lighting, motorhomes, yachts, traffic lights, automatic power supply, as well as in houses where there is no central power supply and, accordingly, the possibility of connection. An ideal option that, for little money, allows you to create an autonomous power grid and use various electrical appliances, even far from civilization.

If the solar system is equipped with batteries, then it is important to pay attention to the following parameters:

Rated voltage of panels: 24V or 12V:  open-circuit voltage value (denoted Vic), which characterizes the amount of voltage generated by the Solar energy in Australia when there is no load.

An important parameter when choosing a controller;

Current Imp - current at the maximum possible power of the panel.

Why do you need a network power plant Energovolt ?

To start with, a network solar power plant is a good way to significantly reduce the monthly payment for electricity, given the constant rise in the cost of energy. This equipment does not require drives and is specially tuned for savings. This type of Energovolt power plants are in particular demand among owners of commercial real estate, because the cost of 1 kWh is much higher compared to the private sector.

Private households are also showing interest in network power plants, because electricity can be sold at a "green tariff". That allows you to save well on utility bills, spending the family budget more economically and reasonably. Despite the price of 1 kWh, as well as the price of periodic maintenance and all the costs of installing a solar station, this investment is more than profitable. Indeed, for a long service life (panels up to 30 years), the power plant will pay for itself more than once, however, for more detailed calculations, you need to know the exact configuration.

Wiring diagrams

There are 3 possible schemes that will help connect Energovolt Solar Panel Sydney to each other: parallel, serial, and series-parallel. More on each of the schemes below.

1. Parallel connection

In order not to make a mistake, you just need to connect terminals of the same sign to the outputs and inputs of the panels. The most convenient type Y connectors.

Thanks to this scheme, it is possible to increase the current, while not increasing the voltage of the panels. For example, there are 4 panels from Energovolt and each 12V, at a voltage of 22.48V, the maximum current is 5.42A. By measuring the open circuit voltage and the rated voltage, you can see that the indicators have not changed. However, the maximum power looks like 5.42A * 4 \u003d 21.68A.

 2. Serial connection

It can be seen from the diagram that the negative terminal from the first panel is connected to the positive terminal of the second, and the negative terminal of the second to the third terminal and further according to the same scheme. With this connection, the voltage indicators of the panels are summed up. The circuit will even achieve an indicator of 220V, but this is done extremely rarely.

3. Series-parallel connection

The above diagram contains panels that are partly connected in parallel and partly in series. This feature allows you to select the most optimal mode of operation of the power plant, thanks to the regulation of the output current and rated power.

How to connect miniature circuit breaker (MCB) for DC 12-1000V

What is the DC miniature circuit breaker (MCB)?

How to connect DC MCB correctly?

Does AC MCB apply to DC states?

What is the DC miniature circuit breaker (MCB)?

The functions of DC MCB and AC MCB are the same. They both protect electrical appliances and other load equipment from overload and short-circuit problems, and protect the circuit safety. but the usage scenarios of AC MCB and DC MCB are different. It generally depends on whether the voltage used is alternating current states or direct current states. Most of DC MCB uses some direct current systems like new energy, solar PV, etc. The voltage states of DC MCB is generally from DC 12V-1000V.

The difference between AC MCB and DC MCB by only physical parameters, the AC MCB has labels of the terminals as LOAD and LINE terminals whereas the DC MCB will have positive (+) or negative (-) sign on its terminal.

How to connect DC MCB correctly? Due to the DC MCB has a marking of ‘+’ and ‘-’ symbol only, it is often easy to connect incorrectly. If the DC miniature circuit breaker is connected or wired incorrectly, there are possibilities of problems occurring. In case of overload or short circuit, the MCB will not be able to cut the current and put out the arc, this may lead to the breaker burning out.

Therefore, DC MCB has a marking of ‘+’ and ‘-’ symbols, still need to mark the circuit direction and wiring diagrams, as shown below:

According to the wiring diagram, 2P DC MCB has two wiring methods, one is the top is connected to the positive and negative poles, another method is the bottom is connected to the positive and negative poles as the marking of ‘+’ and ‘-’. For 4P 1000V DC MCB has Three wiring methods, according to different usage states, to choose the corresponding wiring diagram to connect the wiring. Does AC MCB apply to DC states?

The AC current signal is continuously changing its value for each second. The AC voltage signal changes from positive to negative in every second of a minute. The MCB arc will be extinguished at 0 Volts, the wiring will be protected from a huge current. But the DC signal is not alternating, it flows in a constant state and the value for the voltage is only changed when the circuit is trip OFF or the circuit is decreased by some value. Otherwise, the DC circuit will supply a constant value of voltage for each second of a minute. So, as there is no 0 Volt point in a DC state, it doesn’t suggest that AC MCB applies to DC states.

Connection of BMS123 with AMETEK Latching relay

This diagram shows the connection of the AMETEK Latching Relay with BMS123.

The relay is controlled by the BMS123 Load Relay NC contact. The auxiliary relay is powered by the DC main voltage and it will create the impulse signal for the latching relay to disconnect. 

Since the main coil of the AMETEK Latching Relay is powered by 12V, the 12V voltage is taken from the 4th cell (12V DC) and must be separately protected by a DC breaker. 

After the disconnection it is necessary to press the START button to resume the function. There is also the STOP button to make the manual disconnect.

Please note the fusing in this circuit:  two main fuses on the DC power line, one circuit breaker on the DC main for the auxiliary relay and the second circuit breaker on the 12V line for the latching relay.

Electrical Fuses And Their Types

Electricity is getting more and more advanced every day, but certain things can never change. A few devices are the reason electricity works and operate smoothly without any danger. Many things make up an electrical system.

A fuse is an electrical device used to protect circuits from overcurrent or overload and even protect the circuits. Fuses come in a lot of different designs and colors, but their functioning is the same. Here are electrical fuses and their types:

1.Cartridge Fuses

Cartridge fuses are used to protect electrical appliances such as air conditioners, motors, refrigerator pumps, etc. this is best where high voltage rating and currents are required. They are available up to 600A and 600V AC which are even nicer. 

They are used in industries and commercial areas also as home distribution panels since they are efficient and work best for bigger sizes. Fuses help make it smoothly work without causing any danger. 

2.D-Type Cartridge Fuse

D-type fuses contain an adapter ring, cap, base, and cartridge. Here the fuse base is connected to the fuse cap, where the cartridge is kept inside the fuse cap. The circuit is completed when the tip of the cartridge makes contact with the help of the fuse link conductor.  

These fuses are efficient and help with the smooth functioning of the whole system since they are so safe and strong. 

3.High Voltage Fuse

HV fuses are used in power systems to protect the power transformer, instrument transformer, and distribution transformer where circuit breakers might not save the whole electrical circuit.

High voltage fuses are rated for more than 1500V and go upto 13V. The element of this fuse is made out of copper, silver, or tin. The chamber should be filled with boric acid in case of expulsion type. 

4.Bolted Type Fuses

These fuses, also known as plug-in fuses, come in a plastic body and two metal caps to fit in the socket. They are mainly used in automobiles for wiring and short circuit protection purposes. 

Glass tubes are widely used in the automotive industry. The ratings of these are as low as 12V to 42V. In these types of fuses, the fuse base is directly connected and helpful in many ways.

5.Surface Mount Fuse

SMD fuses, also known as electronic fuses, are mainly used in DC power applications, like hard drives, cameras, DVD players, etc. They are put where space playing is an important part because SMD fuses are tiny and hard to replace.

These fuses are very helpful and make the whole system function without risk of any failures or short circuits. 

Check IndoAsian out; they have some high-quality electrical products from switch devices to circuit breakers and distribution boards that will last you a long time. They are also budget-friendly, which makes them even more popular.

AC Generators are useful appliances that supply electrical power during a power outage from national grid and prevent discontinuity of daily activities or disruption of business operations. Generators are available in different electrical and physical configurations for use in different applications. This work develops a design, Construction and Characterize fuelless AC Generator that generates electrical energy from an alternator interfaced with an inverter. The prime mover is DC electric motor which was connected to the alternator armature shaft. The DC electric motor was powered by rechargeable 24V 75Ah battery, and as it rotates it provides energy to the alternator resulting in generation of AC voltage. Part of the output voltage was rectified to provide 12V for recharging of the battery for it not to be drained. The other part was connected to which was connected to an inverter to provide 220V to the output circuit breaker for the utility load. A control panel was also in cooperated for monitoring and regulation for output voltage. The results were obtained using multi meter to read the output voltage at different load conditions and also measure the voltage output from different components of the control circuit. This gave stable 220V output voltage which was connected to load.
