The Schneider Electric A9D83616T is a single-module (18 mm wide) Acti9 ISPN Vigi RCBO — a residual current breaker with overcurrent protection, combining a C-curve MCB and a 30 mA earth-leakage trip in one clip-on DIN-rail unit. It protects a 1P+N final subcircuit against overload, short-circuit, and earth faults, all in the panel space of a single MCB. The 30 mA earth-leakage sensitivity provides personal protection against indirect contact.
Clip-on mounting to DIN rail or chassis, 18 mm per pole (2 × 9 mm pitches). Upstream terminals accept 1 to 25 mm² rigid or 1 to 16 mm² flexible; downstream takes 1 to 16 mm² rigid or 1 to 10 mm² flexible. Tunnel-type terminals — torque upstream to 3.5 N·m, downstream to 2 N·m. Strip length: 14 mm upstream, 13 mm downstream. IP20 finger-safe front, pollution degree 2 — standard for enclosed distribution boards. The toggle gives clear ON/OFF local indication and is padlockable with a Ø 4 mm padlock for lockout-tagout. Rated for 6000 electrical and 10,000 mechanical cycles.
Compliant with AS/NZS 61009.1. Tropicalisation class 2. This is an IEC-standard device for 50 Hz TN networks.
