Ksd301 16A Bimetal Temperature Switch High Limit Thermostat for Electric Griddles

The thermal protector is a compact bimetal thermal switch designed to protect motors, transformers, pumps, fans and electrical appliances from overheating. It opens the electrical circuit when the protected component reaches the preset action temperature.

The thermal protector uses an internal bimetal element to sense temperature. When abnormal heat causes the protector to reach its preset action temperature, the bimetal element snaps and opens the contacts to interrupt power. After the temperature drops to the reset temperature, the contacts close automatically and power is restored.

Yes. Bimetal thermostat is widely used as a motor protector in electric motors, pumps, fans, vacuum cleaners, power tools and household appliances. It is commonly installed close to the motor winding or heat source to provide responsive overheat protection.

Thermal switch is primarily a temperature protection device rather than a standalone fuse. It responds to heat generated by overload, locked rotor conditions or abnormal operation. For applications requiring direct overcurrent protection, it should be used together with suitable electrical protection components where necessary.

When selecting a thermal protector, consider the action temperature, reset temperature, rated voltage, rated current, protected component temperature, installation position, case type, lead wire specification and insulation requirements. The selected temperature should be based on the actual operating temperature of the motor or electrical equipment.
