It carries a 24 VDC coil rated at 10 A, and is sized for 18.5 kW at AC-2 duty on 400 V or 11.4 kW at 690 V.
The 690 V rating (11.4 kW) covers line-to-line loads on 690 V systems, typical in European industrial networks. Coil hold is at 24 VDC nominal; the 10 A rating at that voltage means the coil draws about 0.42 A steady-state, so a standard 24 VDC power supply with 1 A per contactor leaves headroom.
Width is 55 mm, depth 115 mm, height 112 mm — fits a standard S2 footprint. Screw terminals accept solid wire from 0.5 mm² up to 4 mm² (two per clamp) and stranded from 0.75 to 25 mm² (two per clamp). Strip length for stranded is roughly 10–12 mm depending on ferrule; the 2x 25 mm² capacity means you can parallel feeds for higher current.
