100000 Cycles HCET-B Bimetallic Thermostat HCET-A HC25 Bimetallic Thermostat HCET-A5
BH series thermostat / Miniature thermal protector / Rechargeable battery thermostat
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, its status changes due to over-temperature or over-current conditions, either cutting off or switching on the circuit. BH series provide enhanced safety compared to standard protectors, with no temperature effect lag during sudden high-current conditions.

BW series thermostat / KSD9700 thermal protector / BW9700 temperature protector
H20 and H21 series universal and enhanced protectors feature large metal casings and are composed of thermal conductive metal casing, bimetallic parts welded with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat resistance cables. During abnormal operation, when environmental temperature increases to the set value, the bimetallic parts perform quick action, opening the contact points and disconnecting the circuit. When the device cools to safe operating temperature, the contact points automatically close and normal operation resumes.
