S12 frame, 225 mm deep — panel clearance check
The 3RT1476-6LA06 is a Siemens SIRIUS contactor in the S12 frame size, meaning it handles the higher current ranges typical of large motor loads — pumps, conveyors, compressors — in industrial control panels. At 225 mm deep, 160 mm wide, and 214 mm tall, it needs a back-panel clearance of at least that depth plus the 20 mm forward arc space and 10 mm side gaps for safe arc quenching and heat dissipation. Side-by-side mounting is allowed — no mandatory spacing between units, which saves rail space in multi-contactor assemblies.
Power terminals: 70–240 mm² stranded, screw-type coil
Main power terminals accept stranded copper from 70 mm² up to 240 mm² — that's the range for feeding a large motor starter or feeding through a bus. The magnet coil uses screw-type terminals, which the maintenance team knows: no special tooling, just a screwdriver for coil replacement or voltage change. That covers most PLC output and relay interposing needs without an add-on block.
Active production — sourced per RFQ
Lifecycle stage is current — Siemens still manufactures this contactor, so it's a standard BOM line, not a legacy scavenge. Mechanical endurance is 10 million cycles typical, which aligns with the 10–15 ms arcing time and 60–100 ms operate/release times for reliable motor starting duty. No stock-holding claim — the RFQ confirms the lead time.
