The S12 footprint — 214 mm high, 160 mm wide, 225 mm deep — is sized for a 400 V motor branch that needs more than the S10 can deliver but doesn't justify the jump to the S3 panel cutout. The coil is rated 240-277 V, AC/DC type, with a pickup threshold of 0.8 × rated value and a dropout below that. Arcing time runs 10-15 ms, and the opening times at both AC and DC fall in the 60-100 ms window — consistent for a contactor this size driving an inductive load. The auxiliary contacts are rated for switching: 10 A at 24 V, 6 A at 230 V, and derated down to 0.3 A at 220 V DC. That auxiliary set is what you'd use to signal a PLC input or seal in a holding circuit; verify the DC switching curve if you're breaking an inductive DC load at the higher voltage end. ## Termination reality for the power circuit The main power terminals accept stranded cable from 70 mm² up to 240 mm² — that's a serious conductor, consistent with the S12 frame's current rating. The auxiliary and coil terminals take solid or stranded wire: 2 × (0.5-1.5 mm²), 2 × (0.75-2.5 mm²), or max 2 × (0.75-4 mm²). Fastening is screw fixing, with a single 11 mm hole for mounting. The 3RT1476-6AU36 is listed at the current lifecycle stage — no phase-out notice, no NRND flag. That means it's still a valid BOM line for new builds and spares.","metaTitle":"Siemens 3RT1476-6AU36 SIRIUS Contactor, S12, 240-277 VAC/DC","metaDescription":"Siemens 3RT1476-6AU36 SIRIUS S12 contactor, 240-277 VAC/DC coil, rated operational current for AC-3 duty.
