Enhancing safety against electric shock and leakage faults
The ABB GS201 AC‑C16/0.03 is a residual current circuit breaker with overcurrent protection (RCBO). It combines the functions of a miniature circuit breaker (MCB) and a residual current device (RCD) in one unit for enhanced electrical safety. This device protects electrical circuits against overloads, short circuits, and earth leakage faults, making it suitable for residential, commercial, and light industrial distribution applications. The AC‑type residual current detection provides reliable protection against AC leakage currents.
