Motor Thermal Protection Switch is intended to protect around the heat and overload behavior of a motor through starting, steady running and fault conditions. The source also lists generators, power supplies, power tools, UPS equipment and other driven products as possible matching applications.
Motor Thermal Protection Switch reference values are 125VAC / 250VAC / 32VDC, 50-60Hz AC, 1500VAC/1min dielectric withstand, 3× rated-current switching capability and 25°C ±3°C test ambient. The buyer should additionally define rated current, fixing position, wire route and terminal direction for the actual motor.


Gan'en Electronics can compare a drawing, prototype or current protector and supply the bimetal core through to the assembled protection part. Regular samples are free excluding freight. MOQ is 10,000 pcs, with typical production of about 7 days standard or 15 days customized.
Motor Thermal Protection Switch approval should include an installation and operating trial in the target motor. Incoming/process/final/outgoing checks are followed by a complete pre-packing inspection; third-party inspection is available and the product carries a 30-day warranty.
