The 18 mm width matches a single modular DIN-rail pitch, so it occupies one slot on the 35 mm symmetrical DIN rail alongside the breaker it controls. The 12-24 V AC/DC control voltage covers standard 24 V control transformers and 24 V DC power supplies used in most industrial panels. The 18 mm width (one modular pitch) and 73.5 mm depth fit the standard Acti9 DIN-rail footprint — no extra space needed beyond the breaker's own slot. The screw-clamp terminals accept up to 2.5 mm² rigid or 1.5 mm² flexible wire, with a 9 mm strip length and 1 N·m tightening torque, matching typical panel wiring practice.","metaTitle":"A9N26478 Acti9 MX Shunt Trip 12-24 V AC/DC, 18 mm","metaDescription":"A9N26478 Acti9 MX shunt trip release, 12-24 V AC/DC, 18 mm wide, EN/IEC 60947-2.
