HM232D DC Miniature Circuit Breaker ( DC MCB )

This DC MCB Was designed for direct current(DC) control circuit applications,used for short -circuit and over-current protection within appliances or electrical equipment.

It provide optimization products for DC system applications such as

1. In large capacity, high voltage power system or power plants,DC system offer steady power supply for relay protection, operation control, signal and emergency lighting audio equipment .Mini dc circuit breaker will guarantee the safty of the power system 

2. PV ,EPS,UPS Power system

3. Special Rapid analysis DC circuit breaker is important for rail transit and electrocar

4. In Marine power system,Dc circuit breaker is one of the most important components  to  ensure the safety of power supply system and electrical equipment of ships.
