## Description

This 3A panel mount push button single pole circuit breaker uses a snap-acting bimetal element to sense current overload. As the bimetal snaps through in response to an overload, it opens the electrical contacts and allows the reset button to pop out. The circuit remains disconnected until someone pushes the reset button, closing the contacts and re-energizing the circuit. Designed for protection of industrial circuitry up to 250V AC or 50V DC voltages. Requires a 12mm mounting hole.18mm label plate.
