FSTB KSD303 Bimetal Thermostat 250v 10a Water-proof Defrost Thermostat Refrigerator Parts

Product Description

       KSD303 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.

 

 

 

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.
