Schneider ACTI9 RCCB 63A 2P 300mA A9kR14263

Schneider ACTI9 RCCB 63A 2P 300mA – Fire-Safety & Earth Leakage Protection for Single-Phase Power Systems (A9KR14263)

The Schneider ACTI9 RCCB 63A 2P 300mA – A9KR14263 is a high-reliability residual current circuit breaker built to protect single-phase electrical installations from earth leakage faults, insulation failures and electrical fire hazards. Part of the globally trusted ACTI9 protection series, this RCCB delivers reliable fault detection, fast tripping and long-term electrical safety across residential, commercial and industrial environments.

With a 63-amp current rating, this model is designed for heavy-duty electrical loads, making it suitable for equipment such as air-conditioning units, industrial and commercial power circuits, UPS systems, motors, pump panels, heavy lighting circuits and high-load residential power networks.

The 2-pole (2P) design, protecting both Phase and Neutral, ensures full isolation during leakage faults, enhancing personnel and equipment safety. The 300mA leakage sensitivity classifies this device as a fire-safety RCCB, ideal for installation-level protection where persistent leakage current could overheat wiring and potentially lead to an electrical fire — especially in long cable runs or heavy-load circuits.

Integrated with Schneider’s cutting-edge ACTI9 technology, the A9KR14263 features fast tripping characteristics, high resistance to voltage fluctuations and long operational life. The DIN-rail modular design ensures easy installation into any standard distribution board or control panel.

Whether it’s a new electrical setup or a safety upgrade, the Schneider ACTI9 RCCB 63A 2P 300mA guarantees superior reliability, fire-safety protection and peace of mind for demanding single-phase systems.
