The coil accepts 36 V AC or DC, which simplifies control wiring if your panel already runs a 36 V control bus. The contactor is 3-pole, size S12, with bar connections for the main circuit and screw terminals for the auxiliary and control wiring. The auxiliary contacts are 2 NO + 2 NC, enough for a holding circuit plus a status feedback pair. The Substance Prohibitance date of 03/01/2017 aligns with RoHS compliance milestones. No further compliance documentation (UL, CSA, CE) is explicitly listed in the spec record, but the SIRIUS series typically carries those marks — verify against your local panel certification requirements. Size S12 means the contactor occupies a wider footprint on the DIN rail than the S00 or S0 frames. Plan for side-by-side mounting clearance: the S12 requires 6 mm spacing to grounded parts at the side. The bar connections on the main circuit accept larger conductor cross-sections typical for high-current motor feeders — screw terminals on the auxiliary side handle the control wiring.","metaTitle":"Siemens 3RT5076-6AC36 SIRIUS Power Contactor, 250 kW AC-3, 3","metaDescription":"Siemens 3RT5076-6AC36 SIRIUS power contactor, 250 kW AC-3 at 400 V, 36 V AC/DC coil, 3-pole size S12 with bar connections and screw terminals.
