As we all know, three phase motor is the core component of a device, the whole device will stop running if the motor fails, so it is very important to ensure the safety and stability of the motor, therefore, the requirements for motor protectors used in motors are very strict. Motor Thermal Protector can be effective, reliable and stable for motor equipment.

Three phase motor is installed in the motor attached to the winding, direct sensing winding temperature, when the temperature is about to exceed the limit, the temperature control switch action cut off the contactor coil loop, so that the motor power. As long as the motor overheats and overflows for various reasons, the motor thermal protector can directly play a role in protecting the motor, and the protective effect of the thermal protector is greater than that of the thermal relay.
