TeSys F power contactor, 1400 A AC-1 — end-of-life sourcing note
The Schneider Electric TeSys F LC1F1400V7 is a 3-pole contactor rated 1400 A in AC-1 utilisation category, meaning it's sized for resistive loads like large heating banks or industrial furnaces where inrush is minimal. The 400 VAC 40-400 Hz coil draws 2200 VA inrush and 36 VA hold-in. Rated operational voltage extends to 460 V DC, and the contactor carries IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1 approvals — accepted across European, North American, and Japanese (JIS C8201-4-1) jurisdictions. Plate-mounted for bolted busbar connections — power circuit accepts bar up to 100 x 5 mm. The 438 mm width and 332 mm height demand a generous panel footprint; not a DIN-rail part. Tightening torque on the power circuit is 58 N.m, control circuit 1.2 N.m.
Lifecycle status: end-of-life — sourcing through independent channels
The LC1F1400V7 is flagged end-of-life (EOL). The 1600 A gG fuse recommendation at ≤ 440 V and the 8 kA short-time withstand (10 s at 40 °C) remain valid for legacy replacements, but verify the specific duty cycle against the original installation.
Heat dissipation runs 36 W total, with 150 W per pole in AC-1 duty. The 100-170 ms opening and 40-75 ms closing times are typical for a large frame contactor; coordinate with upstream short-circuit protection (1600 A gG fuse) for selective coordination. Operating altitude reaches 3000 m without derating. Ambient temperature range is -5 to 40 °C operating, -60 to 80 °C storage. Overvoltage category III and impulse withstand voltage of 8 kV suit fixed-installation power distribution.
