Using Circuit Breakers with Surge Protectors

Circuit breakers are necessary, and many experts need them to prevent circuit fire caused by short circuit current.

In contrast, surge protectors protect the appliances from a voltage spike. They are optional, but experts do recommend preventing strikes.

Difference between amps and volts:

While the wires can handle a certain level of amps, appliances handle a significant amount of volts.

Circuit Breaker Vs. Surge Protectors 

The job of a circuit breaker is to prevent circuit fire caused by a short circuit current.

The fire is most likely to occur when there’s too much current flowing through the wires, leading to overheating and later a fire. This is because wires can only handle a certain amount of electric current. Many causes lead to overheating wires, such as a short circuit, too many appliances relying on one circuit, grounded circuit, etc., which is why surge protector breakers are necessary.

Similarly, appliances can also handle a certain amount of volts. When it exceeds, it leads to a power surge that causes damage.

A variety of factors can cause power surges. Some include electrical storms, faulty wiring, power outage, bad electrical components, large appliances in use, etc. For this reason, experts mostly recommend using a surge protector device that protects the device mostly during voltage spikes. In addition, you can install a whole-home surge protector in the box of the electric circuit breaker or at the main point of entry. It protects the appliances by detecting high voltage spikes and diverting the excessive current through the grounding path safely. You can buy these circuit breakers from the best circuit breaker manufacturer to ensure you get the quality you need.

Benefits of having a Surge Protector’s Dedicated Breaker:

  • It allows power to the surge protector that removes it without interrupting the power of other loads.
  • If a component fails inside the protector, only the circuit breaker will trip, and the power of any other load will not be disturbed.

Miniature circuit breakers are known to protect only from voltage spikes for a short period, whereas the circuit breaker protects overcurrent in the wiring.

If there is over-voltage, it can damage the appliance. However, over-voltage will not cause any fire if a circuit breaker is powering it. Surge protectors are simply protecting to limit these surge spikes for a few minutes.

Circuit breakers protect from overcurrent, which can even burn down the house, and this may even happen without overvoltage.

Hence, both circuit breakers and surge protectors are working on protecting different events. If a circuit is tripping, it is usually because there’s much load on the same.

Type of breakers with surge protectors

  • Standard breakers perform well with surge protectors, which means passing high amplitude current and not tripping. The breaker should not be tripping during a power surge and disconnecting the surge protector.
  • High inrush breakers perform even better than the standard ones. However, they even cost five times more than standard breakers. These may require a discrete enclosure to fit the circuit breaker.
  • Professionals don’t highly recommend using the Grand fault circuit interrupter, i.e., GFCI, AFCI, i.e., arc fault circuit interrupter, and combination AFCI with surge protectors. However, they can co-exist with standard breakers.
  • Ground fault circuit interrupter breakers sense ground faults and can trip when a protector redirects current to the ground. Arc fault circuit interrupter breakers sense for Line to Neutral and Line to Grounds arcs; they may also trip during a power surge. And the same will happen with combination arc fault circuit interrupters.
  • In specific surge protection, you will need a stand-alone breaker to ensure a safe and secure system. A stand-alone breaker is not a part of the load center. You can usually use this setup with large switchgear where other small branch breakers don’t exist.

In conclusion, circuit breakers that have type D time-current have outperformed the standard breakers. Even though they have a higher price, the high capacity of surge currents does the performance in even critical applications.

A 100A breaker will lead to higher costs, increased wire costs, and more time for installation. The larger breaker may not coordinate properly with the central lug. A fault found in the protector can also lead to the panel’s breaker tripping.

Application of Circuit Breakers  

  • They include being used in industries
  • They include being used in industries, building, and commercial projects for switching of loads.
  • To help keep the electrical components safe and the system safe, it is important to protect the system with the help of circuit breakers.
  • MCB is the most common circuit when it comes to low voltage circuits. There are multiple smaller circuits within a single circuit. Each of them is controlled with an MCB, so only the affected circuit will be disconnected if any issue arises.

On the other hand, an AC Contactor helps in controlling the flow of electricity throughout the unit. It is one of the most common low power voltage appliances produced by GEYA. It is used in controlling motor frequently and is an important element in connecting and breaking lines.

In some cases, even you can use fuses in a series with the surge protector. But unlike the circuit breakers, you should gang up the fuses. In some cases, it might be advantageous. However, if a fuse block comes into use, all the other fuses must be extracted carefully before power is entirely removed from the surge protector.

Surge Protection Device

Under the extensive range of circuit breakers, GEYA also provides surge protection devices that are a part of the electrical protection system. It is connected parallel to the supply circuit of the load that it needs to be protecting.

    I appreciated it when you shared that a circuit breaker is important as it helps to prevent circuit fire caused by short circuit current. My neighbor just mentioned the other day that she is worried about her house as it keeps on getting power cut lately due to unknown reasons. I will suggest to her hiring a reliable electrician to help inspect and provide the necessary solution to the issue.

    Thanks for helping me understand that standard circuit breakers will work well with surge protectors. I guess I need to let the professionals handle this kind of job to pick the right tools and products. I just need some circuit breakers for my air conditioning unit and my refrigerator to prevent any electrical accidents in the future.

    Thank you so much for sharing this. Very helpful. When there’s a surge, resistance drops. So the MOV will start channeling into the live wire instead so that the surge will not reach any connected device. If you need one, the best surge protectors come with circuit breakers and universal outlets. For instance, this Panther surge protector comes from 1.75 to 5 meters with a maximum capacity of 2,500 watts. This means you may connect up to six devices at the same time without worrying about.

    This is why basic knowledge of circuit breakers are very important. Circuit breakers are a key element in the electrical system of a house. Whenever there is a problem in an individual circuit, the circuit breaker breaks the connection and saves the appliance, and prevents other disasters.

    I had hope to see if your surge arresters require an MCB in the case of a failure. It shows them as being connected directly over the mains – which is fine – but as I have seen others than DO require protection, I had hoped for specific guidance – eg: “MCB is not required to protect the Surge Arrestor as it has an internal fusbile link to protect from a direct short in the case of catastrophic failure” – or other such comment.

    I am guessing this is the case (as you show it directly over the incomer), just would have liked to see a comment confirming it.

    Heh ho 🙂
