Spring-loaded terminals on the main circuit accept 2x (0.25–2.5 mm²) solid or stranded wire — no screw torque to verify, which speeds panel wiring. ## Switching ratings and coordination Rated for AC-3 motor switching at 5.5 kW across 400 V to 690 V. AC-4 at 400 V handles 8.5 A for reversing or inching duty. For type 2 coordination, a 20 A gL/gG fuse is specified; type 1 allows a 35 A fuse.","metaTitle":"Siemens 3RT1017-2JB42 SIRIUS Power Contactor, S00, 24 VDC Co","metaDescription":"Siemens 3RT1017-2JB42 SIRIUS power contactor, size S00, 24 VDC coil with diode suppression, 10 A rated at 24 V.

The main difference is the coil voltage — the 3RT1016-2AP02 uses an AC coil, while the 3RT1017-2JB42 uses 24 V DC with an integrated diode. If the control circuit is already 24 V DC, no rewiring is needed; if it was AC, the coil supply must be changed."},{"question":"What compliance documentation does the brand provide for 3RT1017-2JB42?","answer":"As a SIRIUS product, Siemens typically provides RoHS, REACH, and CE declarations, plus UL/CSA listings.
