The 3RF33 series mounts on standard DIN rail. The 105 x 27 x 122 mm envelope (L x W x H) means it occupies a single 27 mm module width — plan for that footprint in the panel layout alongside other SIRIUS control gear. The 24 V DC coil draw is low enough that a standard PLC output can drive it directly, but check the inrush if driving from a relay output card.

Product details
Frequently asked questions
What catalog classification codes does this part carry?
Group Code R711 and Product Group 3725. These are Siemens internal codes useful for cross-referencing in legacy BOMs or when searching the SIRIUS catalog.
What compliance documentation is available for this part?
RoHS compliant since 15 January 2024. REACH Article 33 disclosure applies: lead (CAS 7439-92-1) above 0.1% w/w is present. Export control is AL: N / ECCN: 9N9999 — no special license required for most destinations.
What is the closest alternative in the same family?
Within the SIRIUS 3RF33 family, the key variant decision is the control voltage. This 24 V DC version is the standard PLC-compatible choice. A 110-230 V AC coil variant exists for the same 15 A AC-15 rating if the control circuit is line-voltage. The mounting footprint and terminal layout are identical, so swapping requires no panel rework.
