The A9E15542 is an Acti9 iERL extension for changeover relay from Schneider Electric. It is rated 10 A at 230 V AC (cos Phi = 1) with a 12 V AC 50/60 Hz control circuit voltage, and mounts on a 35 mm symmetrical DIN rail. This part is now obsolete per the manufacturer.
Schneider has marked the A9E15542 as obsolete.
Tunnel-type terminals accept 0.5…6 mm² conductors via clip connection. Depth is 70 mm, height 88 mm. IP20 rated — suitable for enclosed panel use only, not washdown or outdoor locations.
Rated operational current is 10 A at 230 V AC (cos Phi = 1) across 1 C/O + 1 NO signal contacts. Electrical durability is 100,000 cycles under AC-21 duty. Control circuit draws 8 VA inrush and holding — no derating curve needed for that steady-state load.
