Product Description
ST-22 SEKI Thermal Protector KSD9700 Thermal Switch Temperature Switch
The KSD9700 BW-ABS Thermal Protector is a bimetallic thermostat temperature controller designed for reliable over-temperature and over-current protection. Sealed firmly with small internal resistance and no noise, it automatically resets when safe operating conditions return.
Principle and Structure
The BW & BH series protectors feature a bimetal element that responds to temperature and current changes. When abnormal conditions occur, the bimetal changes state to either cut off or restore the circuit. BH series offer enhanced safety with no temperature effect lag during sudden current surges.
