KSD301 Bimetal Thermostat Auto Reset Thermal Fuse with 100000 Cycles and Normally Closed or Open for Temperature Controlled Applications

The KSD series thermostat operates on the principle of bimetal discs snapping into action when sensing temperature changes. This snap action activates internal contacts to open or close the circuit. Key features include fixed working temperature, reliable snap action, minimal flashover, long service life, and low radio interference.
