The 24 V DC coil and spring-loaded terminals are standard for this class. Auxiliary contacts are 1 NO + 1 NC, built into the contactor — no add-on block needed for basic status feedback or interlocking. The S0 frame size (99 x 45 x 106 mm) fits the standard DIN-rail footprint for this class, so it swaps into an existing panel slot without re-drilling the mounting plate. The S0 size is common across the 3RT2 family, so if you are replacing an older S0 contactor from another Siemens series, the footprint and terminal layout are likely identical. Spring-loaded terminals accept 0.2–2.5 mm² conductors (solid or ferruled stranded) — strip length is typically 8–10 mm for cage clamps. The multi-unit packaging (8 units per pack) suggests this is the bulk ordering variant for OEMs or panel builders who need multiple identical contactors on a line. ## Compliance documentation RoHS compliant since 01-10-09. REACH Article 33 duty-to-inform data is available per the current candidate list. The product group code is 5336 and the group code is R711 — these are Siemens internal classification codes used for catalog sorting and cross-referencing in their ordering system.","metaTitle":"Siemens 3RT2025-2BB40-Z W97 Power Contactor, 17 A, 7.5 kW /","metaDescription":"Siemens 3RT2025-2BB40-Z W97 power contactor, AC-3e/AC-3 rated 17 A, 7.5 kW / 400 V, 3-pole, 24 V DC coil, 1 NO + 1 NC auxiliary contacts, spring-loaded terminals, size S0.
