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.
