The contactor measures 214 mm high, 160 mm wide, and 225 mm deep — a substantial frame that needs generous enclosure space and proper gland-plate planning. Minimum clearance distances around the contactor are 10 mm upwards, 10 mm downwards, 10 mm at the side, and 20 mm forwards — essential for arc flash containment and heat dissipation during the 10–15 ms arcing time. ## Coil and Auxiliary Details The DC coil operates at 110 V rated value with a pickup/dropout ratio of 0.7 (initial value), meaning it holds in reliably down to about 77 V. Solid conductor connections accept 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), and max 2x (0.75–4 mm²) — standard panel wire sizes, no special ferrules needed for the smaller gauges. ## Operating Conditions and Life Switching frequency reaches 600 operations/hour at AC-1 and 250 at DC-1. The lifecycle stage is current, meaning Siemens still actively produces this part.","metaTitle":"Siemens SIRIUS 3RT1476-6XF46-0LA2 Contactor S12, 110 VDC Coi","metaDescription":"Siemens SIRIUS 3RT1476-6XF46-0LA2 contactor, size S12, 110 VDC coil.
