Product Description
KW9700 HCET-B HCET-A HC25 HCET-A5 Thermal Fuse Temperature Controller Thermostat
BW & BH series thermal protectors provide reliable protection against over-current and over-temperature conditions. These devices are firmly sealed, feature small internal resistance, operate silently, and reset automatically. When current flows through the temperature-sensitive bimetal component, abnormal conditions cause the bimetal to change state, either cutting off or restoring the circuit. BH series offer enhanced safety compared to standard protectors, with no temperature effect lag during sudden high-current conditions.

H20, H21 Series Thermostat Principle and Structure
H20 and H21 series universal and enhanced protectors feature large metal casings and consist of thermal conductive metal casing, bimetallic components welded with silver alloy contact points, conductive brackets, insulation fixation stands, fixed contact strips, and heat resistance cables. During abnormal operation, when environmental temperature reaches the set value, the bimetallic components 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 restore normal operation.
