Part identity and deployment context
The Schneider Electric A9D37210 is an Acti9 iC60 RCBO — a combined residual-current circuit breaker with overcurrent protection, in a 2-pole (2P) configuration rated at 10 A with 30 mA earth-leakage sensitivity, B-curve trip characteristic, and a 10 kA Icn breaking capacity at 230 V AC. The integrated earth-leakage protection covers both protected poles, making it a single-device solution for outgoing circuits requiring both overcurrent and residual-current protection.
The 10 A rated current (In) with B-curve magnetic tripping (3–5 × In, i.e. 30–50 A instantaneous) suits resistive and light inductive loads where inrush is modest — lighting circuits, small motor starters, or general socket outlets in residential or light commercial distribution. The 30 mA earth-leakage sensitivity provides personal protection against direct contact, meeting the standard requirement for socket-outlet circuits in most IEC-based installations. Breaking capacity is rated at 10 kA Icn per EN/IEC 61009-2-1 at 230 V AC, with a higher 15 kA Icu per EN/IEC 60947-2 — the Icn figure governs coordination with upstream devices in a typical domestic or commercial panel; the Icu rating gives headroom for industrial distribution where fault levels may be higher.
Tunnel-type terminals accept 1–35 mm² rigid or 1–25 mm² flexible (with or without ferrule); wire-strip length is 12 mm for top or bottom connection. The toggle provides local signalling for ON, OFF, and fault-trip positions.
