The M9R12225 is a 2‑pole residual current circuit breaker (RCCB) from Schneider Electric’s Multi9 GFP series, designed specifically for original equipment manufacturers (OEMs) and control panel builders in industrial and tertiary buildings. Rated at 25 A with a nominal sensitivity of 100 mA (86 mA per UL 1053) and featuring an instantaneous Type A‑SI (Super Immunised) protection class, this device offers robust protection against electric shock from direct contact and mitigates fire hazards in electrical installations. The A‑SI classification provides superior immunity to nuisance tripping caused by transient disturbances, lightning surges, and electrical noise, making it particularly suited for electrically noisy industrial environments. A red mechanical status indicator on the front panel clearly signals a fault trip, simplifying troubleshooting and reducing downtime. The RCCB is compliant with both IEC/EN 61008‑1 and UL 1053 standards, offering a rated breaking and making capacity (Im/IΔm) of 1,500 A and a conditional rated short‑circuit current (Inc/IΔc) of 10 kA with a 100 A gG fuse. Its voltage‑independent tripping technology ensures reliable operation even in degraded supply conditions. The device mounts on a standard DIN rail, occupies 4 modular pitches (36 mm width), and offers IP20 protection at the terminals, becoming IP40 when enclosed in a modular cabinet. With a wide operating temperature range from -25 °C to +60 °C and a mechanical endurance of 20,000 cycles, this RCCB is built for longevity and reliability. Environmentally, it carries Green Premium compliance, with a total lifecycle carbon footprint of 19 kg CO₂ eq. and a recyclability potential of 59%.
