In fact, if you are curious about what a DC circuit breaker is and how it works, you have come to the right place. Let’s explore DC circuit breakers and their purpose below.

What is a DC Circuit Breaker?

A DC (direct current) circuit breaker is an essential component of any building and is designed to protect any electrical devices or equipment that is connected to direct current. DC refers to an electrical charge that flows in one direction, usually obtained via solar cells, batteries, etc. 

You will typically find DC circuit breakers used for larger devices such as solar panels, power bars, and switchgear. The size of the DC circuit breaker that you need will depend on the size and type of unit that it will be protecting. 

How Does a DC Circuit Breaker Work?

DC circuit breakers automatically operate on electrical switches which interrupt the circuit if the direct current is heading towards an unsafe level. This helps to prevent fires, overheating of devices, melting of devices, and other electrical-related hazards. Power surges can also cause blown fuses. 

Once a DC circuit breaker interrupts the electrical flow, you might need to manually reset the circuit breaker. This is done by simply flipping the switch. Keep in mind that some devices might also need to be turned off before the circuit breaker can be reset.

Any building that uses electricity should have circuit breakers installed, and this can include DC circuit breakers, as well as AC (alternating current) ones. After all, you can end up saving money in the long run by installing a circuit breaker instead of having to replace a blown fuse.
