Product details

The Schneider Electric A9N18588 is an Acti9 Vigi C120 add-on residual current device (RCD) designed for 4-pole (4P) circuits. 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.

Frequently asked questions

What is the closest alternative to A9N18588 in the Acti9 family?

Within the Acti9 Vigi C120 range, the A9N18588 is the 4P, 125 A, Type A selective, 500 mA variant. 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.

What compliance documentation does Schneider provide for A9N18588?

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.

Where can I buy A9N18588 and how is it quoted?

The A9N18588 is sourced and quoted to order against an RFQ through independent industrial-automation distribution. Availability and current pricing are confirmed at quote time — no stock count or price is listed here. Submit an RFQ for a firm commercial offer.
