The headline AC-1 rating is 11 A at 480 V — that's the resistive load curve, so it handles heaters, lighting banks, and transformer primaries up to that current. For motor duty (AC-3), the rating is lower; the part is sized for the load, not the contactor frame. Wire range accepts solid or stranded 1 to 10 mm² (roughly 16 to 8 AWG) for the main contacts, and the auxiliary contact wiring can take 2x 0.5 to 2.5 mm². That covers most panel interconnections without needing reducers. The operating temperature span of -25 to +60 °C means it's fine inside a non-climate-controlled cabinet as long as it's not right next to a heat source.
The S0 frame is 85 mm tall and 141 mm deep. Side clearance to adjacent devices is 6 mm; vertical clearance above and below is 10 mm.
