The M9R11225 is a 2‑pole residual current circuit breaker (RCCB) from Schneider Electric’s Multi9 ID range, designed to provide reliable protection against electric shock from direct or indirect contact and to mitigate fire risks in electrical installations. Rated at 25 A with a 30 mA earth‑leakage sensitivity and an instantaneous AC‑type tripping characteristic, this device is specifically tailored for standard AC circuits where detection of sinusoidal residual currents is required. It is dedicated to original equipment manufacturers (OEMs) and panel builders in industrial and tertiary buildings, offering a compact and dependable solution for distribution boards. The RCCB features a red mechanical status indicator on the front panel that clearly signals a fault trip, simplifying troubleshooting and reducing downtime. With a conditional rated short‑circuit current (Inc/IΔc) of 10 kA and a rated breaking and making capacity (Im/IΔm) of 250 A, it ensures robust performance in typical installation environments. The device mounts on DIN rails, occupies 4 modular pitches (36 mm width), and offers IP20 protection at the terminals, becoming IP40 when enclosed in a modular cabinet. It is built with halogen‑free plastic parts, is PVC‑free, and complies with RoHS and REACh regulations, carrying a total lifecycle carbon footprint of 18 kg CO₂ eq. with a recyclability potential of 59%. The M9R11225 is CE‑certified and meets IEC/EN 61008‑1 standards, making it a reliable choice for OEM applications requiring both personnel and fire protection.
