The 48 V AC control coil (40-400 Hz) pulls in at 1070 VA inrush and holds at 9.9 VA; the operating limits are 0.85-1.1 Uc for pickup and 0.2-0.55 Uc for dropout at 55 °C, so verify your control transformer sizing against the inrush figure if the coil circuit is shared with other loads. Rated insulation voltage is 1000 V per IEC 60947-4-1, with an impulse withstand of 8 kV (overvoltage category III), so it's suitable for direct panel connection on 400 V or 690 V line supplies. The 4 NO main poles are rated for 275 A continuous in AC-1; for motor duty (AC-3) the power dissipation per pole jumps to 12 W vs 25 W in AC-1, reflecting the higher switching stress of inductive loads. ## Mounting, wiring, and panel integration This contactor mounts to a plate (not DIN rail), so factor in drilling and tapping for the 4-point baseplate. Dimensions are 208.5 mm wide × 174 mm high × 181 mm deep — it's a substantial frame that needs clear access for the power circuit connections. Power terminals accept bar (25 × 3 mm busbar), ring lugs, or bolted connections for up to 150 mm² cable; the tightening torque is 18 N·m on the power side. Control circuit wiring uses screw clamp terminals accepting 1-4 mm² flexible or solid, torqued to 1.2 N·m. The IP2X front face with shrouds meets IEC 60529 and VDE 0106 for finger-safe front access. Heat dissipation runs 8-9.8 W total, with 25 W per pole in AC-1 duty. In a sealed enclosure, that heat adds up — allow ventilation or derating if the panel ambient exceeds 55 °C. The TH protective treatment indicates tropicalisation for humid environments, which is standard on TeSys F contactors but worth noting if the gear lives in a non-conditioned plant space. The contactor is designed and certified to IEC 60947-4-1, EN 60947-4-1, IEC 60947-1, EN 60947-1, and JIS C8201-4-1. Rated breaking capacity is 1480 A per IEC 60947-4-1. Associated fuse protection is 200 A aM or 315 A gG at ≤ 440 V. The average impedance per pole is 0.33 mΩ at Ith 275 A, 50 Hz. For cross-border compliance documentation (RoHS, REACH, UL), the manufacturer's standard declarations apply — confirm with your compliance team if specific cert copies are needed for your jurisdiction.","metaTitle":"Schneider Electric LC1F1854E7 TeSys F Contactor, 275 A AC-1,","metaDescription":"Schneider Electric LC1F1854E7 TeSys F contactor, 275 A rated operational current in AC-1, 48 V AC 40-400 Hz coil.
