The Schneider Electric A9N16262 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 xID range, rated at 80 A with 100 mA earth-leakage sensitivity. It operates on a 400–415 V AC 50 Hz network and provides Type AC protection — meaning it detects sinusoidal AC residual currents only, suited for circuits without non-sinusoidal or pulsating DC fault profiles.
Integration Notes
Neutral is on the left. Local signalling shows ON, OFF, and fault trip status. A padlocking device can lock the toggle in the OFF position for isolation during maintenance — the device is marked as suitable for isolation (EN/IEC 61008-1). IP20 finger protection means it is intended for enclosure mounting — not for wet or dust-exposed locations. The ambient storage range is -40 to 85 °C, and the unit is tropicalised to class 2 per IEC 60068-1 (95 % RH at 55 °C).
