KSD303 Electric Circuit Breaker Thermostats 10A 250V Temperature Switch refrigerator Parts
Product Description
KSD303-D series snap-action defrost thermostat is a kind of miniature waterproof and hermetically seal bimetal thermal protector. It is of single-pole single-throw structure and works under resistive load.
Thermostat is enveloped in cold-resistant and flame-retardant plastic tube or sealing gum for possible underwater applications.
The product series is widely used as heating compensated switch or automatic defrosting control switch in air-cooling frostless refrigerators.
According to different structures, KSD303 series is divided into five sub series as: KSD303-A, KSD303-D.
KSD303-A:
KSD303-D :
Advantages:
- High durability
- No breakdown, no flashover.
- Every product will be tested, extremely high temperature pass rate.
- High precision.
- Water proof.
- Assemble the fuse and thermostat in one product .

Installation and Direction for Use:
- In the event that the thermostat is employing contact temperature sensing, its cover shall be adhered to the installation position of a controlled appliance.
- The cover shall show no cave-in or deformation resulting in operating temperature variation or bad influence on other performances.
- No excessive force shall be applied to working parts, to prevent them from defects such as cracking base, distorted terminal and wire lead coming off.
- The plastic envelope must be kept intact in the course of installation and usage.
