Bimetal thermal protector high-power temperature switch 150°C

​Thermal protector Features

The bimetal thermal protector has the advantages of low resistance, fast temperature sensing, rapid action, safety and reliability, and small size.

Working principle of thermal protector:

When working, the bimetal element is in a free state, the moving contact and the static contact are closed, and the circuit is turned on. When the electrical appliance heats up for some reason, and the temperature rises to the rated operating temperature of the product, the bimetallic element is heated to generate internal stress and act quickly. Push the contact to open the contact and cut off the power supply, thereby playing a protective role. When the temperature drops to the product's rated reset temperature, the bimetallic element returns to the initial state, the movable contact is closed, and the electrical appliance resumes work, and this cycle is repeated.

Thermal protector application:

The bimetal thermal protector is suitable for washing machine motors, air conditioner fan motors, clothes dryer motors, water pump motors, mixer motors, soymilk machine motors, transformers, electronic ballasts, power tools, microwave oven motors, range hood motors, electronic components, Battery packs, electric heating appliances, etc.
