The Schneider Electric LX1FL350 is a replacement contactor coil from the TeSys range, designed for LX1F contactor frames. It operates on a 350 V AC control circuit at 50/60 Hz, with no built-in suppressor module — so you'll need to add external suppression (RC snubber or varistor) across the coil terminals if driving it from a PLC output or electronic controller. Rated for continuous duty, it delivers 5 Mcycles mechanical durability and a maximum operating rate of 1200 cycles per hour at 55 °C. That's a solid 20 operations per minute — enough for most conveyor cycling and pump start/stop sequences, but not for high-speed pick-and-place applications where you'd want a DC coil or a dedicated fast-switching contactor.
Because it's a standard TeSys accessory, availability is generally stable through distribution. No pin-compatible direct alternative exists in the same family at this voltage — the LX1FL line is voltage-specific, so swapping to a 380 V or 400 V coil means changing the order code entirely.
Mounts directly onto the LX1F contactor magnet assembly — no adapter plate needed. The coil terminals are clearly marked A1/A2 per IEC 60947-4-1. Wire with 1.5 mm² minimum for the control circuit; the inrush current at 350 V AC can pull several amps momentarily, so don't share the control transformer with sensitive electronics without isolation. No built-in suppressor means the coil's inductive kickback is your problem. If the contactor is switched by a PLC relay output, install a properly rated RC snubber (0.1 µF + 100 Ω, 630 V) across A1-A2 to protect the output. For hard-wired pushbutton control, the arc across the stop button contacts will be noticeable — a varistor (e.g., Schneider VZ3) extends button life.
