Tips: How Does DC Circuit Breaker Work?

As their name suggests, direct current (DC) circuit breakers protect electrical devices that operate on direct current. The significant distinction between direct current and alternating current is that the voltage output in DC is constant. In contrast, the voltage output in alternating current (AC) cycles several times each second.

For my power system

I work in a power plant. I bought this DC circuit breaker for my power system. This circuit breaker works very well. I have used it for half a month. Other colleagues also think it is very practical.
