Product details

It handles 9 A at 400 V, good for a 4 kW three-phase motor load. The 24 V DC coil keeps the control circuit isolated from the power side — common in PLC-driven panels where a 24 VDC supply is already on the DIN rail. Size S0 footprint with screw terminals. The 1 NO + 1 NC auxiliary contact set covers basic feedback to the controller without needing an add-on block.

RoHS compliance is confirmed since October 2009. The part carries standard export control classifications AL: N and ECCN: N, so no special licensing for cross-border shipment.

At 9 A AC-3, this contactor matches a 4 kW motor at 400 V three-phase. If your motor is larger, you need the next frame up. The coil draws about 4.5 W holding, typical for a 24 VDC SIRIUS S0 contactor, so factor that into your 24 VDC power budget. The screw terminals accept up to 4 mm² conductors. Upright mounting position is specified, so if you're laying the panel on its back for servicing, derate or verify airflow.

Pack dimensions are 85 x 65 x 55 mm — fits a standard S0 slot on the rail. The auxiliary contacts are on the front face, accessible with the main wiring in place.
