It carries a 24 VDC coil and is rated for AC-3 duty at 11 kW on 690 V and 10 kW on 500 V — the figures that govern real motor switching, not just the thermal current.
The AC-3 motor-switching rating is the one that matters for most BOM lines: 11 kW at 690 V and 10 kW at 500 V. This contactor handles induction motors up to those power levels in standard starting duty. For short-circuit coordination, type 2 (no damage to the contactor) requires a 25 A gL/gG fuse upstream; type 1 (contactor may need replacement) allows a 63 A gL/gG fuse. That's a practical difference when designing a panel with selective coordination requirements.
Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid conductors. For AWG, that's 2x (16 to 12), 2x (14 to 10), or 1x 8. Side-by-side mounting is permitted with 6 mm spacing at the side — no derating required for adjacent units in the same row. Front protection is IP20, which is standard for enclosed panels; the terminal area itself is IP00, so live parts are exposed when the contactor is not inside an enclosure. That's normal for panel-mount gear but worth noting for any maintenance access.
The SIRIUS platform is widely stocked globally, so lead times are predictable for this frame size. No need to broker or hunt surplus — genuine is genuine through any authorized channel.
