9700K Thermal Fuse KSD9700 Auto Reset Thermal Fuse BW9700 Bimetallic 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 bimetallic element, abnormal conditions cause the bimetal to change state, either opening or closing the circuit as required.
BH series protectors offer enhanced safety compared to standard protectors, as they eliminate temperature effect lag during sudden high-current conditions.

BW Series Thermostat / KSD9700 Thermal Protector / BW9700 Temperature Protector
H20, H21 Series Thermostat Principle and Structure
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 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 normal operation resumes.
