The MCCB/MCB is a widely used electrical device in power systems to protect circuits from faults such as overloads and short circuits.
The MCCB/MCB usually consists of two parts: a magnetic trigger and a thermal trigger. Magnetic triggers are used to detect high current transients in circuits, while thermal triggers are used to detect long term overloads in circuits.
The magnetic trigger detects large current transients in the circuit, while the thermal trigger detects long These two parts work together to ensure that power is cut off in the event of a circuit fault, thereby protecting electrical equipment and personnel.
