The OFOM Series RCBO is a highly integrated modular safety protection device that combines the overcurrent and short-circuit protection functions of a miniature circuit breaker with high-sensitivity residual current (earth leakage) protection into a single unit. This product is strictly designed and manufactured in accordance with IEC international electrical standards, featuring a compact integrated housing structure. It is specifically designed to provide "one-stop" electrical safety protection for final circuits in single-phase AC low-voltage power distribution systems, effectively preventing equipment damage, electrical fires, and personal electric shock accidents caused by circuit overloads, short circuits, or earth faults.
