The contactor mounts via screw fixing (four 11 mm holes) and accepts stranded power wiring up to 240 mm², sized for the higher current draw of an S12 frame. ## Dimensions and Wiring — Panel Fit At 225 mm deep, 160 mm wide, and 214 mm tall, this S12 contactor needs a substantial enclosure depth — verify your cabinet's internal clearance before committing the BOM. The screw-fixing pattern uses four 11 mm holes, so the mounting plate must be drilled or tapped for that bolt circle. Power terminals accept stranded conductors from 70 mm² up to 240 mm² — that's a heavy cable range, typical for the main circuit on a large motor or a feeder. Auxiliary and coil terminals handle solid or stranded wire from 0.5 mm² to 4 mm² (2x per terminal), which covers standard control wiring without needing reducers. These are the minimum air gaps to maintain around the contactor for arc flash and heat dissipation — don't crowd it against cable ducts or other devices. ## Coil and Switching Performance The coil is AC/DC rated at 440–480 V, with a pickup operating range of 0.8 to 1.1 times the rated value (so 352–528 V for a 440 V nominal coil). Dropout threshold is 0.8 of rated value — below that the contactor opens, which is a standard margin for brownout ride-through. Switching times: arcing duration is 10–15 ms, and the total make/break time (at AC or DC) is 60–100 ms. That's fast enough for most motor starting and interlocking circuits, but not for high-speed DC switching where arc extinction needs a snubber. Auxiliary contact ratings at 24 V: 10 A; at 48 V: 2 A; at 60 V: 2 A; at 110 V: 1 A; at 125 V: 0.9 A; at 220 V: 0.3 A; at 230 V: 6 A. These are the switched current limits for the auxiliary circuit — use them to size your PLC input or relay loads off the contactor's feedback contacts. No official successor has been published for this order code. If you're cross-referencing a panel built around a different SIRIUS size S12 contactor (like the 3RT1264-6AP36-0KA1), the physical footprint and terminal layout may differ — verify the mounting hole pattern and power terminal positions before assuming a drop-in swap.","metaTitle":"Siemens 3RT1476-6AR36 SIRIUS Contactor, Size S12, 440-480V A","metaDescription":"Siemens 3RT1476-6AR36 SIRIUS contactor, size S12, rated 440-480V AC/DC coil.
