Schneider ACTI9 RCCB 63A 2P 30mA A9KR11263

Schneider ACTI9 RCCB 63A 2P 30mA – High-Sensitivity Shock & Earth Leakage Protection for Single-Phase Circuits (A9KR11263)

The Schneider ACTI9 RCCB 63A 2P 30mA – A9KR11263 is a high-sensitivity residual current circuit breaker engineered to provide superior human safety and protection against electric shock, earth leakage and insulation failure in single-phase electrical installations. Designed under Schneider’s globally trusted ACTI9 protection technology, this RCCB delivers fast and precise fault detection to ensure both user safety and equipment security in residential, commercial and industrial environments.

With a 63A current rating, this model supports heavy-load single-phase circuits, making it suitable for applications such as air-conditioners, industrial and commercial lighting systems, UPS power, distribution circuits, heavy appliances, pump motors and workshop power lines. The 2-pole configuration (Phase + Neutral) guarantees full isolation of both conductors upon fault detection, ensuring maximum operational safety.

The 30mA leakage sensitivity provides life-protection class detection, responding instantly to even minor leakage currents that can pose a risk of electrocution. This makes the A9KR11263 ideal for safety-critical environments including residential buildings, offices, hospitals, educational institutions, shops, hotels, commercial establishments and industrial workplaces where human protection is a priority.

Built to Schneider’s robust ACTI9 engineering standards, this RCCB ensures fast trip response, high electrical durability, stable performance and long operational life. The compact modular format allows convenient DIN-rail installation in any standard single-phase DB, control panel or switchboard.

Whether for new electrical installations or upgrading an existing distribution network, the Schneider ACTI9 RCCB 63A 2P 30mA guarantees industry-leading safety, compliance and reliability with zero maintenance requirements.
