For AC-3 motor duty — the standard squirrel-cage motor start/stop — this contactor is rated 22 kW at 500 V and 11.4 kW at 690 V. The AC-3 maximum mechanical switching rate is 1 000 operations per hour, reflecting the thermal recovery time between starts.
The 24 VDC coil pulls in at 20 to 25 ms and drops out with similar timing — fast enough for most PLC-driven sequences, but not a high-speed DC-switching contactor. The auxiliary contact ratings at 24 V (10 A), 60 V (2 A), 110 V (1 A), 220 V (0.3 A), 230 V (6 A), and 400 V (3 A) cover the typical control-voltage levels found in mixed AC/DC panels. Pollution degree 3 means this contactor is rated for the conductive-dust and humidity conditions typical in industrial enclosures without climate control. The IP20 front and IP00 terminal area confirm it needs an enclosure — it's not a standalone outdoor device. Side-by-side mounting is permitted, which means no derating for heat buildup when contactors are ganged on the rail — but the 55 mm width per unit still governs your DIN-rail budget.
Main circuit terminals accept solid conductors 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²). Stranded conductors up to 2x (0.75 to 25 mm²) fit, and the minimum permissible conductor at 40 °C is 16 mm² — that's the thermal limit for the terminal material, not a crimp restriction. The auxiliary and coil terminals accept 2x (0.75 to 16 mm²) solid or stranded. This covers the typical control wiring range from 1.5 mm² for signal circuits up to 16 mm² for a long coil feed.
RoHS compliance is dated to 05/01/2012, covering the EU RoHS substance prohibitions. The SIRIUS series carries CE, UL, CSA, and IEC certifications as standard for the brand family. No broker or last-time-buy urgency applies.
