This is a circuit breaker designed to protect electrical circuits from damage caused by overcurrent conditions. It features a magnetic (hydraulic delay) mechanism that provides a short time period for the current to decrease before tripping, allowing for the safe disconnection of power. The unit is rated for 22 amperes and can handle voltages up to 277 volts AC or 80 volts DC. Its rocker panel mount design makes it easy to install in various electrical panels.
