ABSTRACT:
An on-board circuit breaker that includes a push-button that enables the circuit breaker to be reset by depressing it, a power supply terminal and distribution terminal, two breaking contacts, and a main bimetal strip. Thermal deformation of the main bimetal strip trips the circuit breaker. The circuit breaker further includes an actuator able to trip the circuit breaker and an electronic circuit monitoring the electric signal. The electric signal is monitored to trip the actuator when predefined particular situations are identified. The circuit breaker also includes a movable reset enable part equipped with a pin. When the circuit breaker is tripped, the reset enable part moves in such a way that resetting the circuit breaker is possible only by depressing the reset enable part before or when the push-button is depressed.
