Dc mcb dc circuit breaker 800v solar breaker

A Miniature Circuit Breaker (MCB) is an automatically operated electrical switch used to protect low voltage electrical circuits from damage caused by excess current from an overload or short circuit. MCBs are typically rated up to a current up to 125 A, do not have adjustable trip characteristics, and can be thermal or thermal-magnetic in operation.

The MDB2Z-63 DC miniature circuit breaker with load isolation and overload/short circuit protection is designed for photovoltaic, energy storage and other DC applications, and is mainly placed between the battery and the hybrid inverter. MDB2Z-63 miniature circuit breakers are rated for operating voltages up to 800 V DC. The circuit breaker adopts a special arc extinguishing and current limiting system, which can quickly disconnect the fault current of the DC distribution box and protect the important components of the solar power generation system.
