Typical applications are: electrical ovens, heating plates, barbeque equipments, industrial usage like welding machines and soldering machines.


When the temperature rises and reaches the fixed operating temperature, a contact system opens (NC) or closes (NO) the electrical current circuit. After cooling down the contact system returns back to its original position (automatically reset function). Within its nominal power conditions the limiter TB 97 works independently from any power supply. If thermal overload protection is needed, a simple, reliable and price competitive solution is available in the TB97. The TB97 is based on reliable bimetal snap-disk technology and specifically designed for applications when high operating temperatures (from 200°C up to 450°C) are required.
Even if the operating temperature is higher than 400°C the tolerance is within ± 15K.
