The Schneider Electric A9E15538 is an Acti9 iRLI changeover relay rated for 10 A at 230 V AC (cos φ = 1) with a 12 V AC 50/60 Hz control circuit. The contact complement is 1 C/O plus 1 NO, wired through tunnel terminals accepting 0.5 to 6 mm² conductors.
The 10 A rated operational current at 230 V AC (cos φ = 1) means it handles resistive loads up to that level. The 12 V AC coil voltage is fixed — verify your control transformer matches. The 2-pole contact set (1 C/O + 1 NO) gives you one changeover and one normally-open signal path. Tunnel terminals accept 0.5 to 6 mm², which covers most panel wiring. IP20 protection means it is for indoor, dry-location panels only.
The A9E15538 is designed to IEC 255 and NF C 45-250, the French standard for control relays. Electrical durability is rated at 100,000 cycles under AC-21 duty (resistive loads).
