KSD301 Bimetal Thermostat Auto Reset Thermal Fuse with Plastic or Ceramic Housing UL/CQC/TUV/RoHS Certified for Household Electric Appliances
The KSD series thermostat operates on the principle of bimetal discs that snap into action when sensing temperature changes. This snap action activates internal contacts to open or close the circuit, featuring fixed working temperatures, reliable operation, minimal flashover, long service life, and reduced radio interference.
