Schneider ACTI9 RCCB 25A 4P 30mA A9KR11425

Schneider ACTI9 RCCB 25A 4P 30mA – High-Sensitivity Life Protection for Three-Phase Electrical Installations (A9KR11425)

The Schneider ACTI9 RCCB 25A 4P 30mA – A9KR11425 is a high-performance residual current circuit breaker built to provide maximum human safety against electric shock, earth leakage and insulation failure in three-phase electrical systems. As part of the globally trusted ACTI9 protection series, this RCCB ensures world-class precision, reliability and long-term electrical safety across residential, commercial and industrial applications.

Rated at 25 amps, the RCCB is suitable for low to medium load three-phase circuits, including commercial lighting networks, power distribution feeders, HVAC units, offices, hotels, workshops, server rooms, machinery control circuits and residential 3-phase supply boards.

The 4-pole configuration (L1 + L2 + L3 + Neutral) offers complete circuit isolation and provides protection across all live conductors. With a high-sensitivity 30mA leakage trip level, the A9KR11425 is specifically designed for protection of human life, detecting even small leakage currents that could result in electrocution — making it a preferred choice in areas where people safety is critical.

Engineered using Schneider’s advanced ACTI9 technology, the device provides rapid and accurate tripping response, ensuring maximum protection during faults without unnecessary nuisance tripping. Compact and modular, the A9KR11425 fits easily on DIN-rail distribution boards and industrial control panels, making installation simple and maintenance-free.

Whether used in homes, commercial buildings, educational institutions, hospitals, hotels, industrial units or infrastructure projects, this RCCB ensures safe power distribution and uninterrupted system reliability.
