A circuit breaker is a device that protects electrical circuits from damage caused by excessive current flow. The Circuit Breaker Magnetic (Hydraulic Delay) is a type of circuit breaker designed for use in applications with alternating current (AC) or direct current (DC) power supply. It has an ampere rating of 10A and can handle voltages up to 600 V AC or 125 V DC. This device features a lever-operated mechanism and is typically mounted on a control panel.
