The Schneider Electric TeSys F LC1F1250ED is a 3-pole contactor rated for 1260 A conventional free-air thermal current (Ith) and 1260 A operational current in AC-1 utilisation category (resistive loads) at 40 °C. The 48 V DC coil draws 9 W holding power and 1600 W inrush at 20 °C. Control voltage limits are 0.85–1.1 Uc for pick-up and 0.2–0.35 Uc for drop-out at 55 °C. The contactor is plate-mounted and carries a TH protective treatment for tropical environments.
Key Ratings & Compliance
Rated operational voltage is ≤ 690 V AC 50/60 Hz, with a rated insulation voltage of 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 Group C. The rated impulse withstand voltage is 8 kV, and overvoltage category III applies. Short-time withstand current (Icw) is 8000 A for 10 s, 5200 A for 30 s, 4000 A for 1 min, 3000 A for 3 min, and 2000 A for 10 min at 40 °C. Rated breaking capacity is 1890 A conforming to IEC 60947-4-1. The contactor complies with IEC 60947-1, EN 60947-4-1, IEC 60947-4-1, EN 60947-1, and JIS C8201-4-1.
Mounting is plate-type (not DIN rail). Overall dimensions: width 12.2 in (309 mm), height 13.3 in (338 mm), depth 10.04 in (255 mm). Power circuit connections are via bar (2 x 100 x 5 mm) or bolted connection; tightening torque for the power circuit is 513.3 lbf·in (58 N·m). Control circuit terminals accept 1–4 mm² flexible or solid wire (with or without cable end). The contactor is rated for operation up to 3000 m altitude without derating and over an ambient temperature range of -5 to 40 °C.
