At 500 V and 690 V the power rating holds at 5.5 kW, which tells you the contactor is thermally limited by the S00 frame size, not by voltage creepage at these levels. The magnet coil draws 3.3 W during both closing and holding — a DC coil that holds at the same power as it picks means no economizer circuit is needed, but it also means the coil stays warm continuously. Verify the 110 VDC supply can deliver the inrush without droop; the holding power is low enough for most 24 VDC-derived supplies stepped up through a DC-DC converter. Short-circuit coordination is specified with Type 1 and Type 2 requirements: Type 2 (no damage to the contactor) calls for a 20 A gL/gG fuse; Type 1 (contactor may need replacement after fault) allows a 35 A gL/gG fuse. This matters when the panel designer is coordinating with upstream motor-protective breakers or fuses. ## Mounting and wiring integration Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail — the 45 mm width per unit is the only horizontal space consumed. The spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded conductors, or 2x (24 to 14 AWG). Strip length is not listed in the spec, but standard practice for spring-cage terminals on this class is 8–10 mm.","metaTitle":"Siemens 3RT1017-2BF42 SIRIUS Power Contactor, 110 VDC Coil,","metaDescription":"Siemens 3RT1017-2BF42 SIRIUS power contactor, Size S00, 110 VDC coil, 45 mm wide, spring-loaded terminals.

The 3RT1017-2BF42's 110 VDC coil and spring terminals make it a distinct variant — a panel wired for 110 VDC control and spring-clamp terminations would need rewiring to accept the 3RT1016-2AP02."},{"question":"What is 3RT1017-2BF42's listed depth?","answer":"The depth is 73 mm. Combined with the 45 mm width and 60 mm height, the S00 frame fits standard 200 mm deep enclosures with room for wiring ducts."},{"question":"What compliance documentation does this brand provide for 3RT1017-2BF42?","answer":"As a Siemens SIRIUS product, the 3RT1017-2BF42 carries CE marking for the European market and is designed to meet IEC/EN 60947-4-1 for contactors. UL and CSA listings are typical for this series, though the specific approvals for this variant should be verified against the nameplate or the manufacturer's declaration of conformity.
