20A 25A KSD302 bimetal thermostat

Constructure and application of ksd302 bimetal thermostat

ksd302 thermostat is the small-size bimetal thermostat series with a metal cap, which belongs to thermalrelays family.The main principle is the fumction 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 ond off finally.

Widely used in household water dispensers, electric heaters, disinfection cabinets, coffee pots, rice cookers, air conditioners, laminators, and other heating equipments.

Advantages ksd302 bimetal thermostat : high stability, high accuracy, small volume, long life cycles, high  reliability, little radio interference.
