AC125V 250V Rated Thermal Overload Protector Switch Micro Motor / Transformer Usage

Thermal motor protector BW9700 250v 5a to 10a 0C to 150C with UL TUV CQC certifiate

BW9700 series thermostat’s Principle and structure

H20,H21serial universal and enhanced protectors with large metal casing are composed of the thermal conductive metal casing, bimetallic parts welded with silver alloy contact point, conductive bracket, insulation fixation stand, fixed contact strip and heat resistance cable. In case of abnormal operation, along with the increase of the environment temperature to the set value, the bimetallic parts perform quick action, open the contact point, and disconnect the circuit. When the device is cooled to the temperature for safe operation, the contact point will automatically closes and recover normal operation.
