It carries 4 normally-open instantaneous contacts, meaning it closes the circuit immediately when the coil picks up, with no built-in delay. That's 4 NO contacts you can wire into a PLC input, a status lamp, or a safety chain without loading the main contactor's auxiliary block.
Rated operational current varies by voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. That 690 V / 1 A rating is what you need for 690 VAC control circuits common in European industrial panels — most auxiliary contactors top out at 400 V. That low-level switching spec matters for direct PLC input sensing — dry contacts at 17 V won't self-clean, so you need a contactor that reliably closes that low-energy circuit. The 10g / 5 ms and 5g / 10 ms shock resistance means it stays closed under moderate vibration on a conveyor drive or compressor skid.
Mounting and wiring in the panel
Fastening is screw and snap-on mounting. The S00 frame size is 45 mm wide, 57.5 mm tall, 111 mm deep. Wire capacity accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid conductors. That covers standard 1.5 mm² control wiring up to 4 mm² for heavier load circuits on the same contact block.
What you get on the front
Front protection class is IP20 — finger-safe terminals but not sealed against water. That -55 °C storage floor means it survives cold warehouse or trucking in winter without damage, even if the panel isn't powered. Substance prohibition date is July 1, 2006, which aligns with the original EU RoHS directive. The part is RoHS-compliant for the standard six restricted substances. No REACH or UL listing is explicitly stated in the evidence, but the SIRIUS series typically carries CE and UL/CSA certification for the broader line.
