DC MCB (DC Mini-circuit breaker) is a device used for direct current circuit protection, usually used in solar power generation systems, wind power generation systems and other DC power systems. The DC MCB has a fast break protection function, which can quickly cut off the power when the circuit is short or overloaded, avoiding damage to electrical equipment or fire danger.
