Thermal circuit breakers are used as safety devices to protect against overcurrents and short circuits in various industrial settings.
They are particularly suitable for applications on transformers, solenoid valves, electrical systems, and low-voltage lines, where precise and safe energy management is essential.

Thanks to their gradual yet effective response, they ensure long life for electrical components and maximum protection for the entire system.

The operation of thermal circuit breakers is based on the action of a bimetallic element, which is sensitive to temperature changes caused by increased current.

When the current exceeds the set threshold, the bimetallic strip heats up and deforms, triggering the trip mechanism.

This process produces a complete galvanic disconnection, safely and controlledly interrupting the circuit.

The thermal response prevents sudden trips during short-term current peaks, ensuring reliable protection while avoiding unnecessary interruptions.
