Application：
DC MCB supplementary protectors are designed to provide over-current protection within
appliances or electrical equipment, where a branch circuit protection is already provided or not
required. Devices are designed for direct current (DC) control circuit applications.
the circuit breaker adopts a special extinguishing and current limiting system,which can quickly
switch off the fault current of the DC distribution system,to protect photovoltaic module,the important
component in solar power generation system from the harm of high DC reverse current and AC feedback
current caused by inverter failure,and ensure the reliable operation of solar photovoltaic power generation system.
