Schneider ACTI9 RCCB 63A 4P 300mA A9KR14463

Schneider ACTI9 RCCB 63A 4P 300mA – Advanced Earth Leakage & Fire-Safety Protection for Three-Phase Systems (A9KR14463)

The Schneider ACTI9 RCCB 63A 4P 300mA – A9KR14463 is a premium-grade residual current circuit breaker engineered to safeguard three-phase electrical installations against earth leakage faults, shock hazards and electrical fire risks. Designed under the globally trusted ACTI9 protection platform, this RCCB ensures high-efficiency protection for users, wiring networks and connected electrical equipment.

With a 63-amp current rating, the RCCB is suitable for heavy-duty circuits such as industrial machinery, HVAC systems, lighting loads, high-power equipment, commercial distribution boards, and residential three-phase connections. The 4-pole configuration (L1, L2, L3 + Neutral) provides complete disconnection of all live conductors in the event of a fault, guaranteeing maximum safety and operational reliability.

The 300mA leakage sensitivity makes this RCCB ideal for fire safety and electrical installation protection, detecting abnormal leakage current and preventing cable overheating — one of the major causes of electrical fire in heavy-load systems.

Built with Schneider’s cutting-edge fault-detection technology, the unit delivers fast response time, stable tripping characteristics and long operational life even under fluctuating load and harsh industrial conditions. Its DIN-rail modular design ensures smooth integration with all standard 4-pole distribution boards and panel enclosures.

Whether used for industrial control panels, commercial buildings, factories, warehouses, hotels, workshops or large residential three-phase systems, the ACTI9 RCCB 63A 4P 300mA provides next-level protection and dependable performance for mission-critical electrical networks.
