Product Description

KSD301 Bimetal Thermostat Normally Closed N.C Adjust Snap Disc Temperature Switch Thermal Control Switch

Product Description

KSD301 snap action thermostat is the small-size bimetal thermostat series with a metal cap, which belongs to thermal relays family. The main principle is the function of bimetal discs snap action under the change of temperature sensed. The snap action of disc can push the action of the contacts through the inside structure, causing the circuit on and off finally. The main characteristics: fixed working temperature, reliable snap action, less flashover, longer working life and less radio interference.
