The 24 VDC coil pulls in at 0.7 of rated voltage and drops out reliably, with operate and release times in the 38–65 ms range. It's built for the SIRIUS modular system, so it shares the same 45 mm width and DIN-rail footprint as the rest of the S00 family. The main contacts are rated 10 A at 24 VDC for resistive loads (AC-1), and the contactor handles switching frequencies up to 1000 cycles per hour on AC-1 duty, 750 on AC-3 motor duty. The S00 frame takes up 45 mm of rail width, 58 mm tall, 73 mm deep — fits in a standard 200 mm deep enclosure with room for gland plates. Clearance: 10 mm upwards and forwards, 6 mm at the sides, 10 mm downwards. Screw-type terminals on the magnet coil accept solid or stranded wire from 0.5 to 4 mm² (single) or two conductors up to 1.5 mm² each. No auxiliary switch block on this variant — it's a bare coupling contactor, so if you need auxiliary contacts, you'll add a separate block from the SIRIUS range.","metaTitle":"Siemens SIRIUS 3RT2016-1JB42 Coupling Contactor, 24 VDC Coil","metaDescription":"Siemens SIRIUS 3RT2016-1JB42 S00 coupling contactor with 24 VDC coil, 10 A at 24 VDC.
