The circuit breaker is a type of electromagnetic device that protects electrical circuits from damage caused by excessive current flow. This particular model features a magnetic-hydraulic delay mechanism, making it suitable for use in applications with varying voltage requirements. It has a maximum current rating of 20A and can handle alternating current (AC) voltages up to 250V, as well as direct current (DC) voltages of up to 80V. The device is designed for mounting on a rocker panel, providing easy access for operation and maintenance.
