The overheat protector is an automatic cut-off switch built into the single-phase motor designed to monitor the temperature of the inner motor. The switch automatically cuts off power if the motor temperature exceeds the maximum allowable operating temperature. The switch will automatically restart once the motor temperature drops to about 60–70℃.
Miniature Thermal Protector
The MT sensor is embedded in every phase of motor winding and transmits a signal to the control panel. Control can be set up to cut off power when the MT is activated, and restart when the MT is deactivated.
The MS is used to detect moisture leakage through the mechanical seals. If moisture is found, the sensor will trigger and transmit a signal to the control panel. The control panel will then set off a warning signal and/or power off to protect the pump motor.
The auto-cut protector is an automatic cut-off switch installed inside the motor. The switch will automatically cut off power to the motor if there is a power surge or if overheating occurs. The switch will automatically restart the motor once the temperature drops to about 60–70℃.
