12 V DC Contactor

The 12 V DC Contactor is a contactor that can work under 12 volts DC voltage, it is mainly used to control the on-off of DC circuit and realize the remote control and protection of the circuit. By controlling the coil of the contactor to energize or de-energize, it can make the contacts of the contactor close or break, thus controlling the on-off of the 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.
