Protection Relays

When the thermal relay is used, it is necessary to connect the thermal relay in series in the main circuit, and the normally closed contact in series in the control circuit. When the motor is overloaded, the current flowing through the thermal element exceeds the set current of the thermal relay, and the heating of the thermal element increases and the temperature rises. , The bimetal sheet is heated and bent, pushing the push plate, so that the normally closed contact is disconnected, and the control circuit is disconnected so that the main circuit is also disconnected, which plays the role of overload protection.
