For motor duty (AC-3), the power dissipation per pole is 12 W, versus 25 W per pole in AC-1 — the contactor runs cooler on motor loads but the AC-1 figure is the headline current limit. The control circuit is AC 60 Hz, with an operational voltage range of 0.85 to 1.1 Uc at 55 °C and a drop-out range of 0.35 to 0.55 Uc — the coil holds in at 600 V AC and drops out reliably below that band. Inrush power is 970 VA at 60 Hz; hold-in power is 66 VA. The coil suppression should match the AC line frequency; verify polarity if a free-wheel diode is added for DC switching. The contactor is plate-mounted (not DIN-rail), so panel integration requires a mounting plate or sub-panel. Dimensions are 7.1 in deep, 8.2 in wide, 6.9 in tall. Power circuit connections use bar or bolted lugs up to 150 mm²; control circuit terminals accept 1 to 4 mm² flexible or solid wire with screw clamp terminals. Tightening torque is 159.3 lbf·in for power and 10.6 lbf·in for control. This contactor is sized for a 275 A resistive load at 440 V, so it typically lives in a power distribution or heating control panel on a mounting plate. Operating altitude is 3000 m without derating; storage temperature range is -60 to 80 °C.","metaTitle":"Schneider LC1F1854X6 TeSys F Contactor, 275 A AC-1, 4-Pole,","metaDescription":"Schneider Electric TeSys F LC1F1854X6 4-pole contactor, 275 A AC-1 at 440 V.
