It carries a single changeover contact (1 C/O) rated for both AC and DC pilot circuits: 6 A at 24 V AC/DC, derating to 1 A at 250 V DC and 3 A at 415 V AC 50 Hz. That multi-voltage curve means one part covers control voltages from 24 V panel logic up to 415 V motor-circuit signalling, so you don't need separate DC-rated and AC-rated auxiliaries on the same rail.
At 9 mm wide — one standard modular pitch — this contact clips onto a DIN rail alongside the host RCBO without stealing an extra slot. The 71 mm depth keeps it flush with the Acti9 breaker body, so it doesn't push into the backplane wiring channel. Screw-clamp terminals accept 0.25…4 mm² rigid or 0.25…2.5 mm² flexible; tighten to 0.6 N·m. Strip 6 mm for the bottom connection.
Designed and certified to EN/IEC 60947-5-1, the standard for control-circuit devices and switching elements. That covers the dielectric strength, thermal endurance, and mechanical endurance expected in industrial panel environments. Storage temperature range is -40…70 °C; operating ambient is -25…60 °C — fine for most indoor enclosures but watch the upper limit if the panel sits near a furnace line or in direct sun.
