Schneider Electric A9D11216 Earth Leakage Circuit Breaker

Schneider Electric A9D11216 is a two-pole Acti9 iC60H2 RCBO (residual-current circuit breaker with overcurrent protection) rated 16 A and 30 mA residual current sensitivity for 240 V AC networks. This device protects a single circuit from both overcurrent and earth leakage, tripping when leakage or overload is detected to inhibit electric shock and equipment damage. The RCBO combines a C-curve overcurrent characteristic with A-type residual-current detection, balancing reliable short‑circuit response with sensitivity to pulsating DC leakage. With a rated short-circuit breaking capacity (Ics) of 10 kA, it is suitable for typical domestic and light commercial distribution applications. The A9D11216 is DIN-rail mountable and designed to fit standard Acti9 busbar and enclosure configurations, providing line and neutral protection in a compact 2P footprint for 240 V installations. As part of Schneider Electric’s Acti9 family, it integrates with other iC60H2 modules and accessories, enabling coordinated protection for multi‑circuit panels while maintaining a streamlined installation and clear status indication on the front face.
