Its 225 mm depth, 160 mm width, and 214 mm height mean it needs generous cabinet space — not a DIN-rail shoehorn. The 11 mm fixing holes and screw-fastening method are standard for this frame class. ## DC switching capability — the numbers that matter This contactor is built for DC loads, with a 110 V DC coil and a rated switching current that drops as voltage climbs: 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. At higher DC voltages like 230 V and 400 V it handles 6 A and 3 A respectively, but the 480 V and 600 V ratings — 180 A and 192 A — look like AC-1 or motor-duty figures, not DC. Watch the duty cycle labels when selecting; the DC-1 maximum switching frequency is 250 operations per hour, versus 600 for AC-1. For inductive DC loads like solenoids or DC motor brakes, factor that lag into your safety circuit timing. ## Thermal limits and terminal capacity The main power terminals accept two conductors per pole, solid or stranded, 0.25 to 2.5 mm² — typical for control wiring up to 14 AWG. Marked as current production — no phase-out notice on record. The SIRIUS S12 platform is widely specified, so this order code is a standard BOM line, not an end-of-life scavenge.","metaTitle":"Siemens 3RT1476-2XF46-0LA2 SIRIUS Contactor, 225 mm Depth, D","metaDescription":"Siemens SIRIUS S12 contactor 3RT1476-2XF46-0LA2, 225 mm depth, 160 mm width, DC coil 110 V, screw fixing, -40 to +70 °C, current production.
