BW AID thermal protector 250V 5A 50 150C temperature thermostat

Product Overview

Description

BW series thermostat / KSD9700 thermal protector / BW9700 temperature protector

1. 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.
