Schneider ACTI9 RCCB 25A 2P 30mA – High-Sensitivity Shock Protection for Single-Phase Installations (A9KR11225)
The Schneider ACTI9 RCCB 25A 2P 30mA – Model A9KR11225 is a high-sensitivity residual current circuit breaker designed to protect people and electrical systems against electric shock and earth leakage faults in single-phase supply networks. Part of Schneider Electric’s globally trusted ACTI9 protection platform, this RCCB ensures precision fault detection, fast disconnection and long-term operational safety for homes, commercial setups and light industrial applications.
Rated at 25 amps, this RCCB is ideal for low-to-medium load circuits including household appliances, lighting networks, HVAC units, power sockets, small equipment circuits, office installations, and retail distribution boards. The 2-pole (Phase + Neutral) configuration ensures that both conductors are disconnected during a leakage fault, providing full isolation and superior safety.
With 30mA leakage sensitivity, this device is optimised for life protection, instantly detecting even minor leakage currents that may be harmful or fatal to humans. This makes the A9KR11225 recommended for installations where human safety is the top priority, such as homes, offices, schools, hospitals, hotels, commercial workspaces and public environments.
Built with Schneider’s advanced ACTI9 safety and endurance design, the A9KR11225 offers high mechanical durability, stable tripping characteristics and zero-maintenance performance. The compact DIN-rail modular construction enables quick installation in any standard distribution board.
