FSTB KSD303 Bimetal Thermostat thermal fuse for refrigerator fuse 10A 250V

 

Product Description

  KSD303-A series snap-action defrost thermostat is a kind of miniature waterproof and hermetically seal thermostat sensor. 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.

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.
