KSD301 Snap Action Thermostat

KSD301 Series
KSD301 series snap-action bimetal thermostat is a kind of miniature hermetically sealed bimetal thermostat (1/2″ disc). It is of single-pole single-throw structure and works under resistive load.
KSD301 bimetal thermostat is in wide use in a great variety of compact type home appliances with automatic reset or manual reset to provide temperature control or temperature protection.
KSD301 snap action thermostat series is a small-size bimetal thermostat series with a metal cap,which belongs to thermal relays family. The main principle is that one function of bimetal discs is snap action under the change of sensing temperature. The snap action of disc can push the action of the contacts through the inside structure, then caused on or off of the circuits finally. The main characteristics are the fixation of working temperature, the reliable snap action, less flashover, longer working life and less radio interference.
