BH series thermostat / Miniature thermal protector / Rechargeable battery thermostat
BW & BH series protectors provide reliable protection against over-current and over-temperature conditions. They feature sealed construction, small internal resistance, silent operation, and automatic reset functionality. When current flows through the temperature-sensitive bimetal component, abnormal conditions cause the bimetal to change state, either opening or closing the circuit as needed. BH series offer 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 consist of thermal conductive metal casing, bimetallic components with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat-resistant cables. During abnormal operation, when environmental temperature reaches the set value, the bimetallic components perform quick action to open contacts and disconnect the circuit. When the device cools to safe operating temperature, contacts automatically close to restore normal operation.
