The control circuit draws its power from a separate source, not the breaker's load path. Mounts on a 35 mm symmetrical DIN rail, occupies 18 mm of panel width (one modular pitch), and the depth is 73.5 mm — standard for the Acti9 accessory footprint. The white housing carries a mechanical action indicator so you can see the trip state at a glance. ## Lifecycle reality — obsolete, not gone No official Schneider successor order code exists for this shunt trip variant. The 48 V control voltage is the key fit parameter — it must match your trip-signal source. The part works on both AC and DC at that same voltage, which simplifies wiring in mixed-supply panels. The 18 mm width means it takes one standard DIN-rail pitch; if your panel is tight, that's one less modular slot than a two-pitch accessory. EN/IEC 60947-2 is the standard for low-voltage switchgear and controlgear — specifically the section covering circuit-breaker accessories. That certification tells you the shunt trip has been type-tested for coordination with the host breaker, so you don't lose selectivity or breaking capacity when you add it. The bottom screw-clamp terminals accept 0.5 to 2.5 mm² rigid or 1.5 mm² flexible (with or without ferrule), with a stripping length of 9 mm and a tightening torque of 1 N·m. That's standard for control wiring in a panel — no special tooling needed.","metaTitle":"Schneider Electric A9N26477 Acti9 MX Shunt Trip, 48V AC/DC,","metaDescription":"Schneider Electric A9N26477 Acti9 MX shunt trip release, 48 V AC/DC control voltage.

It is quoted to order against an RFQ; availability and current pricing are confirmed at quote time. No minimum volume is required for a quote."},{"question":"What is A9N26477's listed depth (73.5 mm) on this component line?","answer":"The A9N26477 has a depth of 73.5 mm. That's the dimension from the DIN-rail mounting surface to the front of the housing — standard for Acti9 accessories and compatible with standard distribution panelboards and enclosures."},{"question":"What is A9N26477's listed width (18 mm) on this component line?","answer":"The A9N26477 has a width of 18 mm, which is one standard modular pitch on a 35 mm DIN rail. That's the same width as a single-pole MCB in the Acti9 range, so it fits in the same slot without wasting panel space."},{"question":"What compliance documentation does this brand provide for A9N26477 (RoHS, REACH, UL, IEC)?","answer":"The A9N26477 is certified to EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear accessories.
