The Schneider Electric TeSys F LC1F2254V7 is a 4-pole contactor rated for 315 A in AC-1 utilisation category (resistive load) at ≤440 V, 50/60 Hz. The 400 V AC control coil operates at 40–400 Hz with a closing time of 35 ms and opening time of 130 ms at rated control voltage. It is designed for plate mounting and carries IEC 60947-4-1, EN 60947-4-1, and JIS C8201-4-1 compliance.
The 315 A AC-1 rating governs resistive loads — heaters, lighting banks, or transformer primaries where inrush is minimal. The 4 NO (normally open) power pole configuration means all four poles switch the load; there are no built-in auxiliary contacts. The 400 V AC coil is a non-standard control voltage in many panels (common are 110 V, 230 V, or 24 V DC), so verify the control transformer or PLC output matches before specifying. The plate-mount form factor (181 mm depth, 208.5 mm width, 197 mm height) requires a dedicated backplate or sub-panel — not a standard DIN rail.
Deployment Context
This contactor is sized for industrial control panels switching resistive loads up to 315 A. The plate-mount design and IP20 front face (with shrouds) suit enclosed panel installation where personnel access is limited to qualified electricians. Power circuit connections accept bar, lug-ring, or bolted terminations up to 185 mm² cable or 32×4 mm busbar — typical for main feeder or large heater bank switching. The 8–9.8 W heat dissipation (32 W per pole in AC-1 duty) must be factored into the panel thermal budget to avoid derating at elevated ambient temperatures.
