A thermomagnetic circuit breaker is a protective device used in electrical systems to interrupt the electric current in case of overload or short circuit. It is designed to ensure the safety of electrical installations, equipment, and people operating or near these systems.

Thermal trip: This mechanism protects against prolonged overloads. When the electric current exceeds the nominal value for an extended period, the heat generated in the circuit breaker causes a bimetallic strip to bend, activating the trip mechanism and interrupting the electrical circuit.

Magnetic trip: This mechanism responds quickly to current surges, such as those caused by short circuits. When a very high current passes through the circuit breaker, a magnetic field is generated within the device. This magnetic field moves a movable core which, in turn, activates the trip mechanism, immediately interrupting the electrical circuit.

The combination of these two mechanisms provides effective protection against different types of electrical faults. Thermomagnetic circuit breakers are commonly used in residential, commercial, and industrial electrical systems due to their reliability and ability to protect against a variety of electrical problems.
