This is a circuit breaker designed to protect electrical circuits from overloads. It has a magnetic trip mechanism that delays tripping when the circuit breaker detects an overload, allowing for temporary fluctuations in current. The unit operates at 10 amperes and can handle either alternating current (AC) or direct current (DC), with a maximum voltage of 277 volts AC or 80 volts DC. It is designed to be mounted on a rocker panel.
