SIRIUS 3RT1017-2BB42-ZX95 — Power Contactor, Size S00, 24 VDC Coil
The Siemens SIRIUS 3RT1017-2BB42-ZX95 is a Size S00 power contactor with a 24 V DC magnet coil rated at 3.3 W closing and holding power — a fixed coil draw that simplifies power-supply budgeting in a multi-contactor panel. Spring-loaded terminals on the main current circuit accept 2x (0.25... 2.5 mm²) solid or stranded conductors, or 2x (24... 14) AWG, matching the wire range typical for motor branch circuits up to this frame size. The IP20 finger-safe protection on the front and terminals means the panel builder can leave the front cover off during commissioning without exposing live parts to accidental contact.
Switching Ratings and Duty Class
For AC-4 reversing or inching duty, the rated operating current is 8.5 A at 400 V. The AC-12 maximum operating current is 10 A, covering resistive and solid-state loads. Across the control-voltage spectrum, the auxiliary contact ratings are: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 2 A at 60 V — figures that govern the pilot-duty capability for PLC outputs or relay interfaces. For motor branch-circuit protection, the required fuse coordination is specified: Type 2 coordination calls for a gL/gG 20 A fuse; Type 1 coordination allows a 35 A gL/gG fuse. Pollution degree 3 (industrial environment) is the rated insulation class.
Dimensions are 45 mm width, 60 mm height, 73 mm depth. The 6 mm side clearance is the minimum for side-by-side mounting.
