The Schneider Electric iDPNN C20A ELM is a 2‑pole residual current circuit breaker (RCBO) that combines overcurrent protection (overload and short‑circuit) with earth‑leakage protection in a single compact device. It is designed to protect single‑phase low‑voltage circuits against electrical faults including overloads, short circuits, and leakage currents that could pose a risk of electric shock or fire.
