The S12 frame size (214 mm high, 160 mm wide, 225 mm deep) is a panel-mount unit using screw fixing through an 11 mm hole; it's not a DIN-rail snap-on, so plan for four bolts and a backplate. The DC coil pulls in at 0.7 of rated voltage and drops out with a delay of 80 to 100 ms after power is removed — that dropout delay matters for sequencing in safety circuits where you want a controlled off-sequence rather than an instant drop. Clearance requirements are modest — 10 mm upwards, 20 mm forwards, 10 mm downwards, 10 mm at the side — so it fits in a standard 600 mm deep enclosure with room for wiring ducts. ## Auxiliary Contact Ratings and Switching Capacity The DC auxiliary curve drops to 2 A at 48 V and 60 V, then 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 2 A at 500 V. That's a steep derating as voltage climbs — if you're switching a 125 V DC pilot light, you're limited to 0.9 A, so check the load against the curve before wiring. Maximum switching frequency is 600 operations per hour under AC-1 duty and 250 ops/h under DC-1. ## Environmental Range and Wiring The main power terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire — spring-cage or screw terminals aren't specified here, so confirm the termination style from the full datasheet before panel wiring.","metaTitle":"Siemens 3RT1476-2XJ46-0LA2 SIRIUS Contactor, 72 V DC, 192 A","metaDescription":"Siemens SIRIUS S12 contactor 3RT1476-2XJ46-0LA2 rated 192 A at 600 V AC-1, 72 V DC coil.
