BW-ECM Thermostat BW-ECP Temperature Protector Switch KSD9700 Bimetallic Thermostat
Product Overview
BH Series Thermostat - Principle and Structure
BW & BH series protectors offer protection against over-current and over-temperature conditions. They feature sealed construction, small internal resistance, no noise, and automatic reset functionality. When current passes through the temperature and current-sensitive bimetal, the bimetal's status changes due to over-temperature or over-current conditions, either cutting off or switching on the circuit. BH series protectors are safer than standard protectors as they eliminate temperature effect lag under sudden high-current conditions.

BW Series Thermostat / KSD9700 Thermal Protector / BW9700 Temperature Protector
H20, H21 series thermostat - Principle and Structure
H20, H21 series universal and enhanced protectors with large metal casing are composed of 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 close and recover normal operation.
