Dimensions are 172 mm high, 120 mm wide, 170 mm deep. The 170 mm depth is the key number for gland-plate clearance — make sure your enclosure has that much headroom behind the door. Side clearance of 10 mm and front clearance of 20 mm are needed for arc venting and wiring access. Main power terminals accept stranded wire from 16 to 70 mm². Auxiliary terminals handle 2x (0.5-1.5 mm²) solid or 2x (0.75-2.5 mm²) stranded, max 2x (0.75-4 mm²). That's enough for control wiring up to 4 mm² without pigtails.
Lifecycle stage is marked as current — meaning Siemens still lists it as an active catalog number with no announced end-of-life. That's important for BOM freeze planning: you're not chasing a last-time buy or an NRND replacement.
Auxiliary contacts are built in. Their rated switching capacity at 24 VDC is 10 A, dropping to 0.3 A at 220 VDC. That covers typical PLC and relay interface loads; for DC switching at higher voltages, check the curve against your inductive load. Coil operating range is 0.8 to 1.1 times rated value at 50/60 Hz. Pick-up and drop-out times are 40-60 ms AC or DC; arcing time is 10-15 ms. Those are standard for this frame size — no surprises on timing coordination.
