It is rated for a continuous load current of 125 A and provides earth-leakage protection at 500 mA sensitivity, Type A, with a selective (time-delayed) characteristic. That means it sits at the head of a sub-distribution board or as an outgoer group incomer, coordinating with downstream RCDs so that only the faulted branch trips during a ground fault — the selective delay prevents a whole-panel blackout for a transient or a downstream fault. The device occupies 10 modules of 9 mm pitch, so it needs 90 mm of DIN rail width. Dimensions are 198 mm wide × 95 mm high × 73 mm deep. Tunnel-type terminals accept 1-35 mm² flexible or 1-50 mm² rigid; strip length 15 mm; tightening torque 3.5 N·m.","metaTitle":"Schneider Electric A9N18588 Acti9 Vigi C120, 4P 125A 500mA T","metaDescription":"Schneider Electric A9N18588 Acti9 Vigi C120 add-on RCD, 4P, 125 A, 500 mA Type A selective, 230-415 V AC.

The same physical footprint and electrical ratings apply to other sensitivity or time-delay variants in the Vigi C120 series, but the selective Type A 500 mA combination is specific to this order code. No pin-compatible direct drop-in exists outside the Acti9 Vigi C120 line without verifying the mounting and terminal arrangement."},{"question":"What compliance documentation does Schneider provide for A9N18588?","answer":"The device is certified to EN 61009 and IEC/EN 61009-2-1. Schneider Electric typically provides a Declaration of Conformity covering the applicable EU directives (Low Voltage Directive, EMC) and may include RoHS/REACH compliance statements upon request. The pollution degree 3 rating per IEC 60947-2 is also documented in the product certificate."},{"question":"Where can I buy A9N18588 and how is it quoted?","answer":"The A9N18588 is sourced and quoted to order against an RFQ through independent industrial-automation distribution.
