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.","metaTitle":"Siemens 3RT1017-2BB42-ZX95 SIRIUS Power Contactor, 24 VDC, S","metaDescription":"Siemens SIRIUS 3RT1017-2BB42-ZX95 power contactor, Size S00, 24 VDC coil 3.3 W, spring-loaded terminals, AC-2 5.5 kW at 400 V.
