The headline rating is 275 A at ≤ 440 V in AC-1 utilisation category (resistive load). AC-1 is the continuous-current rating for heater banks, lighting, or transformer primary switching — not motor starting. For motor duty (AC-3), the power dissipation per pole drops to 12 W versus 25 W in AC-1, so the contactor's thermal capacity is sized for the resistive curve. The 4 NO power poles are all normally open; there are no built-in auxiliary contacts on this base unit. The control circuit is a 380 V AC coil rated for 40–400 Hz, with an inrush of 1070 VA and a hold-in consumption of 9.9 VA. The coil pickup range is 0.85–1.1 Uc at 55 °C; dropout occurs between 0.2 and 0.55 Uc. This means a 380 V nominal coil will hold in down to roughly 323 V and drop out between 76 V and 209 V — relevant for brownout coordination in a control panel. The contactor is plate-mounted (not DIN-rail), so panel layout must account for the 181 mm depth, 208.5 mm width, and 174 mm height. Power-circuit connections accept bar (25 x 3 mm busbar), lugs (150 mm² cable), or bolted connections — typical for a panel builder wiring a high-current resistive load bank. The part is certified to IEC 60947-4-1 and EN 60947-4-1 (the contactor standard), plus IEC 60947-1 and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1, with an impulse withstand of 8 kV. The front face carries IP2X protection with shrouds — finger-safe but not washdown-rated. ## Deployment Context This contactor is sized for a 275 A resistive load in a panel — typically a large oven, furnace, or transformer bank. The plate-mount form factor and bar/lug power connections mean it integrates into a busbar system, not a DIN-rail assembly. The 380 V AC coil ties directly into a 380 V control transformer; no DC supply or rectifier is needed.","metaTitle":"Schneider Electric LC1F1854Q7 TeSys F Contactor, 275 A AC-1,","metaDescription":"Schneider Electric LC1F1854Q7 TeSys F contactor, 275 A rated operational current (AC-1), 4 NO poles, 380 V AC coil.
