The coil accepts 200–277 V AC/DC, so it works on either supply without a separate rectifier — simplifies panel wiring when both AC and DC control voltages are present.
Mounts via screw fixing (two 11 mm holes on 145 mm width) onto a vertical panel surface. Dimensions: 210 mm high, 145 mm wide, 202 mm deep. The depth is the main panel-space constraint — allow at least 10 mm clearance at the side and 20 mm forward for arc-chamber venting and wiring access. Main power terminals accept stranded conductors from 70 to 240 mm² — sized for the full S10 current rating. Auxiliary terminals handle 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded, with a max of 2x (0.75–4 mm²). Coil connections are screw-type terminals, not cage clamps.
