It operates on a 1000 V AC 50 Hz control circuit, drawing 550 VA inrush at 20 °C and 45 VA hold-in power at the same temperature. ## Key electrical characteristics The coil has an average resistance of 610 Ohm at 68 °F (20 °C) and an inductance of 68.5 H when closed. Its control circuit voltage limits are: drop-out at 0.35...0.55 Uc and operational range of 0.85...1.1 Uc at 50/60 Hz and 131 °F (55 °C). This means the coil reliably picks up at 850 V AC and drops out between 350 and 550 V AC, which is important for brownout ride-through planning. Operating time is 23...35 ms closing and 5...15 ms opening. That 5 ms minimum opening time is fast enough for most safety circuits but verify it coordinates with your upstream breaker's clearing time if used in a direct-on-line start. ## Thermal and mechanical performance Heat dissipation runs 12...16 W at 50 Hz, so factor that into your panel's thermal budget — a densely packed enclosure with several TeSys F contactors running continuously will need ventilation or derating. That rate suits moderate-speed conveyor or pump cycling but not high-speed stamping press applications. Ambient air temperature for operation is 23...131 °F (-5...55 °C). The coil technology is without built-in suppressor module, so you'll need to add an external RC snubber or varistor across the coil if driving it from a PLC output or solid-state relay to prevent voltage spikes.","metaTitle":"Schneider Electric LX1FF1000 TeSys F Contactor Coil, 1000 V","metaDescription":"Active TeSys F contactor coil, LX1FF1000, 1000 V AC 50 Hz control circuit. 23-35 ms closing, 5-15 ms opening. 10 Mcycles mechanical durability.

There is no pin-compatible substitute with the same 1000 V AC 50 Hz rating; the LX1FF1000 is the specific order code for that voltage. If your control voltage differs, the LX1FF family includes coils for 110 V, 220 V, 380 V, and 480 V AC."},{"question":"How do I source the LX1FF1000?","answer":"This part is quoted to order against an RFQ.
