Directly control the on-off of the circuit through the handle, which is convenient for daily maintenance or quick cut off of the power supply in emergencies. When the current continuously exceeds the rated threshold, the thermal release device inside the circuit breaker triggers a trip to prevent the line from overheating and damage. In response to large currents generated by sudden short circuiting of the line, the circuit will be cut off instantaneously through the electromagnetic release mechanism to avoid equipment damage or fire, It’s also suitable for AC power.
