The 440 VAC control coil (40-400 Hz) pulls 1650 VA inrush and holds at 22 VA. Plate-mounted, it measures 13.3 in high by 12.2 in wide by 10.04 in deep — a substantial footprint that needs panel layout planning. Rated operational voltage is up to 690 V AC 50/60 Hz, with a rated insulation voltage (Ui) of 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C. Short-time withstand current (Icw) is 8000 A for 10 s, 5200 A for 30 s, and 3000 A for 3 min at 40 °C, giving coordination headroom for upstream protective devices. The associated fuse rating is 1000 A gG at up to 440 V. Rated breaking capacity is 1890 A conforming to IEC 60947-4-1. The control circuit operates on AC 40-400 Hz with a voltage range of 0.85 to 1.1 Uc for pickup and drops out between 0.25 and 0.5 Uc at 55 °C. Closing time is 40-80 ms; opening time is 100-200 ms. Maximum operating rate is 1200 cycles per hour at 55 °C. Heat dissipation is 20 W total, with 120 W per pole under AC-1 load — factor that into enclosure thermal management. The LC1F1250R7 is designed and tested to EN 60947-1, IEC 60947-4-1, and JIS C8201-4-1. The protective treatment is TH (tropicalized) for humid environments. Terminal connections: power circuit uses bar connections (2 x 100 x 5 mm); control circuit uses screw clamp terminals accepting 1-4 mm² flexible or solid wire. Tightening torque is 58 N.m for power circuit and 1.2 N.m for control circuit. ## Sourcing this part Given the EOL status, this contactor is sourced through our independent supply network. For a new design, consider evaluating a current-production TeSys contactor with equivalent AC-1 current rating and coil voltage to avoid future obsolescence risk.","metaTitle":"Schneider TeSys F LC1F1250R7 Contactor, 1260 A AC-1, 440 VAC","metaDescription":"Schneider Electric TeSys F LC1F1250R7 3-pole contactor. 1260 A rated operational current (AC-1), 440 VAC 40-400 Hz coil.
