This simplifies panel layout when space is tight. These are the minimum air gaps to maintain for safe operation and arc containment. These timing figures matter when coordinating with upstream protective devices or sequencing multiple contactors. For BOM freeze or PCN watch, the SIRIUS series is a mature, widely deployed platform. Replacement or second-source options within the same size S00 family exist, but any substitution should be verified for coil voltage and auxiliary contact configuration. ## Integration Notes for the Panel Builder The screw terminals accept up to 4 mm² solid conductor, sufficient for motor circuits up to the contactor's rated capacity.","metaTitle":"Siemens 3RT2017-1XB42-0LA2 SIRIUS Contactor, Size S00, 24-34","metaDescription":"Siemens SIRIUS 3RT2017-1XB42-0LA2 power contactor, size S00, 24-34 VDC coil, screw terminals, 30M mechanical cycles, current production.
