11+ Best Thermal Circuit Breakers You Can Buy

 

Thermal circuit breakers, also called thermal circuit protectors are electric devices that use bimetallic strip electrically connected in series with the circuit. The heat produced by the current during an overload deforms the bimetallic strip causing it to “break” and trips the breaker. Thermal circuit breakers have a significant advantage over fuses because they can be reset after tripping. They can also be used as the main ON/OFF switch for the equipment being protected.
