Gewiss – GWD4227R – ReStart RM 2P 16 A Type A RCBO

The GWD4227R ReStart RM by Gewiss is a compact 2‑pole residual‑current circuit breaker (RCBO) that offers combined overcurrent protection with sensitive earth‐leakage detection (Type A, 30 mA). What sets it apart is the integrated ReStart auto‑reclosing module, which after a trip can automatically restore power if the fault is transient—ideal for maintaining continuity. Rated at 16 A with C‑curve magnetic protection and 4.5 kA breaking capacity, it fits standard DIN‑rail panels using just 3 modules.
