The contactor mounts via screw fixing (four M11 holes on a 180×214 mm footprint) and accepts stranded cable from 70 to 240 mm² on the main power terminals. That range covers most motor feeds up to roughly 200 A depending on duty cycle and ambient temperature. ## Coil and auxiliary ratings The coil operates on AC or DC from 200 to 277 V. An auxiliary switch block is built in (screw-type terminals), rated for switching at various control voltages: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 6 A at 230 V. These are the maximum resistive break currents — inductive loads like relay coils will need derating. Arcing time is 10-15 ms, which is typical for a contactor of this size and helps with coordination in a fused or breaker-protected circuit. That covers most panel layouts without needing a special bracket. The 10 mm side gap is tight — verify adjacent components don't exceed that before wiring. The storage limit is mainly for shipping and idle spares, not running duty.","metaTitle":"Siemens SIRIUS 3RT1476-6QP35 Contactor, Size S12, 200-277 V","metaDescription":"Siemens SIRIUS 3RT1476-6QP35 contactor, size S12, 200-277 V AC/DC coil.
