Schneider Electric A9R61463 iID 4P 63A Residual Current Circuit Breaker Acti 9

The Schneider Electric A9R61463 iID is a 4-pole 63A Residual Current Circuit Breaker (RCCB) from the Acti 9 series, engineered to provide dependable earth-leakage protection in industrial and commercial distribution boards. Designed for DIN rail installation, the A9R61463 safeguards personnel and electrical installations against shock hazards caused by earth faults, making it a trusted choice for control panel builders and electrical engineers worldwide.

Technical Specifications

Applications & Use Cases

• Residential & Commercial Buildings: Earth-leakage protection for final distribution boards and sub-boards.
• Industrial Control Panels: Personnel protection against indirect contact in machinery and automation enclosures.
• Three-Phase Installations: Four-pole configuration covers three-phase plus neutral circuits for comprehensive coverage.
• Downstream Circuit Protection: Used upstream of MCBs to provide additional residual current protection for groups of circuits.

Frequently Asked Questions

• What is the difference between an RCCB and an RCBO? An RCCB (like the A9R61463) detects residual/earth-fault currents and disconnects the circuit; it does not provide overcurrent (overload or short-circuit) protection. An RCBO combines both functions in one device.
• Why choose a 4-pole RCCB? A 4-pole RCCB is required for three-phase and neutral (3P+N) circuits, ensuring all live conductors are disconnected simultaneously on fault detection.
• Is the A9R61463 compatible with other Acti 9 devices? Yes — the Acti 9 iID range is designed to integrate seamlessly with other Schneider Electric Acti 9 modular devices on a standard DIN rail.
