Rated switching capacity on the DC side: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. That 10 A at 24 VDC is the headline figure — enough for a solenoid bank or a small DC motor brake in a panel. Spring-type terminals on the coil side accept 0.5 to 4 mm² solid or stranded wire, double up to 2× (0.5 to 4 mm²). The main contacts are rated for 20 to 12 A depending on duty — check the AC-1/AC-3 curves for your load. The 45 mm width and 70 mm height fit the S00 footprint — standard for a compact control cabinet. Depth is 73 mm including terminals. Mechanical operating rate varies by duty: up to 1,000 cycles/hour at AC-1, 750 at AC-2 and AC-3, 250 at AC-4. The AC-3e rating also maxes at 750 cycles/hour. No auxiliary switch block is included (Auxiliary Switch: No). If you need feedback contacts, order the separate SIRIUS auxiliary switch block for the S00 frame.","metaTitle":"Siemens 3RT2017-2VB42 SIRIUS Coupling Contactor, 24 VDC Coil","metaDescription":"Siemens 3RT2017-2VB42 SIRIUS coupling contactor, size S00, 24 VDC coil, spring-type terminals.
