TB02Series miniature thermal protector of small volume, sensitive Operation, long service life, reliable protection, in various types of Batteries, battery pack, sensing cable,overheating micro motor and transformer Overcurrent protection double wide application.

Working Principle:

TB02 Series miniature thermal protector is a bimetallic strip that acts as a heat Sensitive response element, when the temperature or current is increased when the Heat transfer to the two metal sheets, reaches a predetermined temperature Value when it move quickly, the contact is disconnected. The circuit is cut off, when the temperature dropped to a predetermined reset the setted value, The bimetal quickly restored, the contact is closed, connected to the circuit.

Selection parameter:

Range of Action temperature: 40C180C
Temperature tolerances:3,5
