BW-AID thermal protector,BW-AID thermal protector for fan motor
BW series thermostat / KSD9700 thermal protector / BW9700 temperature protector
1. BW series thermostat’s Principle and structure
BW serial 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.
