Description:

 

KSD303-A series auto defrost thermostat is a kind of miniature waterproof and hermetically sealed low temp thermostat for refrigerator. It is of single-pole single-throw structure and works under resistive load. It is enveloped in cold-resistant and flame-retardant plastic tube or sealing gum for possible underwater applications. The product series low temp thermostat is widely used as heating compensated switch or automatic defrosting control switch in air-cooling frostless refrigerators.

 

Advantages:

 

Water proof.

 

High precision.

 

High durability No breakdown, no flashover.

 

Every product will be tested, extremely high temperature pass rate.
