The integrated varistor surge suppressor is built into the coil circuit — no external snubber needed for standard inductive loads. ## Switching capability and coordination For motor loads, the contactor is rated at 5.5 kW at 400 V and 690 V AC-3, and 8.5 A at 400 V AC-4 for reversing or inching duty. With type 2 coordination, use a gL/gG 20 A fuse upstream; type 1 coordination allows a 35 A fuse. The DC coil holds at 1.4 W, closing at 1.4 W — no holding-current drop. ## Wiring and auxiliary contacts Main circuit terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded — AWG equivalents 2x (20-16), 2x (18-14), 1x 12. This unit ships with zero auxiliary contacts (instantaneous contact count: 0), so add a separate auxiliary contact block if feedback or status signaling is needed. IP20 on the front and terminals means finger-safe but not washdown-rated.","metaTitle":"Siemens 3RT1017-1WB42 SIRIUS S00 Contactor, 24 VDC Coil, 10","metaDescription":"Siemens SIRIUS 3RT1017-1WB42 power contactor, size S00, 24 VDC coil, 10 A rated operational current.
