That's the same cage-clamp style you find on many PLC I/O modules — strip to 8 mm, push the wire in, no screw tightening. The AC-3 rating is the one that matters for standard squirrel-cage motors: 5.5 kW at 500 V and the same 5.5 kW at 690 V. That tells you it can handle the inrush and break the running current of a motor up to that power. The auxiliary contact is a single instantaneous contact (1 NO or 1 NC depending on configuration), which is enough for a basic interlock or status feedback but may need an auxiliary contact block if you need more. This matters for panel builders who need to meet IEC 60947-4-1 coordination requirements — pick your fuse size based on whether you want to protect the contactor or just clear the fault.","metaTitle":"Siemens 3RT1017-2BF41 SIRIUS Power Contactor, 110 VDC Coil,","metaDescription":"Siemens 3RT1017-2BF41 SIRIUS power contactor, size S00, 110 VDC coil, spring-loaded terminals, screw and snap-on DIN rail mounting.

The main difference is the coil voltage — verify your control voltage matches before substituting. Both use spring-loaded terminals and mount on 35 mm DIN rail."},{"question":"Will 3RT1017-2BF41 drop into a panel specified around 3RT1016-2AP02 without rewiring?","answer":"Yes, the physical dimensions (45 mm width, 60 mm height, 73 mm depth) and DIN rail mounting are identical across the S00 frame. The spring-loaded terminals accept the same wire sizes, so the main power circuit wiring does not need to change. Only verify the coil supply voltage — this unit uses 110 VDC."},{"question":"Where can I buy 3RT1017-2BF41 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
