This is a plate-mounted contactor (not DIN-rail), so panel integration requires a dedicated mounting plate or sub-panel. The power circuit uses bar connections sized for 100 x 5 mm bus bars; control circuit terminals accept 1-4 mm² flexible or solid wire. Tightening torque is 58 N·m on the power side and 1.2 N·m on the control side. The AC-1 utilisation category covers resistive or slightly inductive loads where the current waveform is nearly in phase with voltage — no motor inrush, no back-EMF. If your load is a motor (AC-3 or AC-4), this contactor is over-specified on current but lacks the arc-chamber design for breaking motor locked-rotor current; stay with the AC-1 application for which it is listed. Heat dissipation is 20 W total, or 120 W per pole in AC-1 duty. The average impedance per pole is 0.12 mΩ at 1260 A, 50 Hz — that low resistance keeps I²R losses manageable at full load, but the 120 W per pole still needs airflow or spacing in the enclosure. Operating time is 40-80 ms closing, 100-200 ms opening. ## Electrical endurance and protection coordination Rated 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 — all at 40 °C. These values define the contactor's ability to pass fault current until an upstream protective device clears. The associated fuse recommendation is 1000 A gG at ≤ 440 V. Rated breaking capacity is 1890 A per IEC 60947-4-1. Impulse withstand voltage is 8 kV, overvoltage category III. Rated insulation voltage (Ui) is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C. The contactor carries TH protective treatment for tropical environments. Ambient temperature range for operation is -5 to 40 °C; storage range is -60 to 80 °C. The LC1F1250U7 is designed and tested to IEC 60947-1, IEC 60947-4-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. These standards cover low-voltage switchgear and controlgear — specifically contactors and motor-starters. The IEC 60947-4-1 standard is the governing document for the AC-1 rating and the short-time withstand values listed above.","metaTitle":"Schneider LC1F1250U7 TeSys F Contactor, 1260A AC-1, 3P, 240V","metaDescription":"Schneider Electric LC1F1250U7 TeSys F contactor. 1260A AC-1 resistive rating, 3-pole, 240VAC 40-400Hz coil.
