Product introduction:
BW thermal protector is composed of dish-shaped highly sensitive bimetallic element, moving contact, static contact, fixed base, metal shell and temperature-resistant electronic conductor. When working, the bimetallic element is in free state, the moving contact is closed with the static plate, and the circuit is switched on. When the use of electrical equipment due to failure or self-heating, the temperature rises to the rated action temperature value of the product (can be set according to the customer for automatic product demand standards), bimetallic components due to the heat of the product internal stress and rapid action, push the moving contact, the contact disconnect, cut off the power supply, electrical stop working, so as to play the role of overheating protection, When the temperature of the protected electrical appliance drops to the rated reset temperature value of the product, the bimetal element will return to the original state and the dynamic contact will be closed, and the electrical appliance will resume working.
