Their functions are similar to total functions of some or all of the electric equipment such as knife switch, overcurrent relay, under voltage relay, thermal relay, leakage protector, etc., and they are important protective devices in the low-voltage power distribution network: 3 The circuit-breakers are internally more sophisticated, but relatively simple in principle. They connect with inductor between the incoming and outgoing lines. When the current exceeds the rated value, the coil drives the iron core to provide protection; 4 After the main contact of the circuit-breakers is manually or electrically closed, the free tripping mechanism locks the main contact at the closing position. Coil of overcurrent tripper and thermal element of thermal tripper are connected with the main circuit in series and coil of under voltage tripper is connected with the power supply in parallel.
