The Schneider Electric TeSys F LC1F2254M7 is a 4-pole contactor rated for resistive load switching (utilisation category AC-1) with a rated operational current of 315 A at ≤ 440 V AC, 50/60 Hz. The 220 V AC control coil draws 1070 VA inrush and 9.9 VA hold-in power. Closing time is 35 ms, opening 130 ms at rated control voltage. This is a plate-mount contactor — no DIN-rail clip — sized for bolted busbar or lug connections on the power side (up to 185 mm² cable or 32 x 4 mm busbar). The 4 NO main poles handle resistive heater banks, lighting, or transformer loads where AC-1 duty applies.
Verify coil voltage, pole count, and AC-1 current rating against the application before substituting.
The 315 A AC-1 rating governs resistive loads only. For motor (AC-3) or inductive duty, the contactor's thermal current Ith of 315 A at 50 Hz and 0.32 mOhm average impedance give a baseline, but the utilisation category must match the load type — this part is spec'd for AC-1, not general-purpose motor starting. Rated insulation voltage is 1000 V per IEC 60947-4-1 (1500 V per VDE 0110 group C), with an 8 kV impulse withstand. Overvoltage category III means it's suited for fixed-installation distribution panels, not downstream equipment. Heat dissipation runs 8 to 9.8 W total, with 32 W per pole in AC-1 duty. The associated fuse recommendation is 315 A gG or 250 A aM at ≤ 440 V — use that for coordinated short-circuit protection.
Plate mount only — 208.5 mm wide, 197 mm high, 181 mm deep. Power circuit connections accept bolted busbar (32 x 4 mm), ring lugs, or connectors for 185 mm² cable. Control circuit uses screw clamp terminals accepting 1 to 4 mm² flexible or solid wire (1 or 2 cables). Tightening torque: 1.2 N·m control, 35 N·m power. Protective treatment TH indicates tropicalisation for humid environments.
