Product Description
Snap-Action Thermostat - Bimetallic Thermostat Thermal Fuse
The KW9700 series snap-action thermostats provide reliable protection against over-current and over-temperature conditions. These sealed units feature small internal resistance, silent operation, and automatic reset functionality. The bimetallic components respond to both temperature and current changes, cutting off or restoring the circuit as needed. The BH series offers enhanced safety with no temperature effect lag during sudden current surges.
