AC/DC Moulded Case Circuit Breaker

The AC/DC Moulded Case Circuit Breaker is an electrical switch with integrated overload protection, short-circuit protection and (in some models) earth leakage protection. It is designed with a molded case, featuring a compact structure, high protection level and long service life. When the current in the circuit exceeds the rated current of the circuit breaker or when a short circuit occurs, the circuit breaker will automatically trip and cut off the circuit, thus preventing the circuit and equipment from being damaged due to overload or short circuit.

Safety Breaker MCCB 3P

The operating principle of the Safety Breaker MCCB 3P is based on the combination of a magnetic trigger and a thermal responder. When an overload or short-circuit occurs in a circuit, the current will increase dramatically, and the magnetic trigger will sense this abnormality and quickly cut off the circuit. Meanwhile, the thermal responder detects temperature changes in the circuit and also triggers the MCCB to cut off the circuit when the temperature exceeds the set value, thus effectively preventing equipment damage and fire accidents.
