The auxiliary contacts are rated for switching at 24 VDC up to 10 A, at 230 VAC up to 6 A, and at 400 VAC up to 3 A — so it can handle both the coil circuit of a downstream contactor and a PLC digital input signal on the same block.
Fastens with screw fixing through an 11 mm hole. The mounting position allows vertical surface mounting with ±90° rotation or ±22.5° tilt front-to-back, so it fits into tight enclosures where the panel isn't perfectly vertical. Power terminals accept stranded cable from 70 to 240 mm² — that's heavy cable, sized for the full rated current of the S10 frame. The auxiliary terminals take 2x 0.5 to 1.5 mm² solid or 2x 0.75 to 2.5 mm² stranded, max 2x 4 mm². Side-by-side mounting is allowed, with 10 mm clearance to the side and 10 mm upward/downward. Overall dimensions: 210 mm high, 145 mm wide, 202 mm deep. That depth is the body plus the arc chamber — plan for at least 20 mm forward clearance for wiring and arc venting.
