The Type A-SI (Super Immunised) classification means it handles pulsed DC fault currents from electronics (rectifiers, VFDs, UPS) while resisting nuisance tripping from high-frequency leakage — a common need on modern mixed-load panels. Clip-on mounting to a 35 mm symmetrical DIN rail — no tools needed for installation, and the 2P (two-pole) form factor occupies 7 modules of 9 mm pitch (63 mm total width). Tunnel-type terminals accept 1…35 mm² flexible or 1…50 mm² rigid cable; tighten to 3.5 N·m with a 15 mm strip length. The IP20 finger-safe enclosure suits enclosed distribution boards — not outdoor or washdown locations. Designed and certified to EN 61009 and IEC/EN 61009-2-1 — the harmonised standard for residual-current-operated circuit-breakers with integral overcurrent protection (RCBOs) and, for this add-on block, the applicable product-specific requirements. Rated insulation voltage (Ui) of 500 V AC 50/60 Hz per IEC 60947-1, with an operating temperature range of -25…60 °C and storage from -40…60 °C.","metaTitle":"Schneider Electric A9N18556 Vigi C120 Add-on RCD, 2P 125A 30","metaDescription":"Schneider Electric A9N18556 Acti9 Vigi C120 add-on residual current device. 2P, 125 A rated current, 300 mA sensitivity, Type A-SI (Super Immunised).
