The LX1FG030 is a replacement contactor coil from the Schneider Electric TeSys F range, designed for AC control circuits at 30 V AC 50 Hz (36 V AC 60 Hz). It pulls in with 805 VA (50 Hz) and holds at 55 VA — the inrush-to-hold ratio tells you the coil's magnetic circuit is well saturated once closed, which is typical for a large-frame contactor. Without a built-in suppressor module, so you'll need to add an external RC snubber or varistor across the coil if driving from a PLC or electronic output; the back-EMF on dropout will arc across semiconductor contacts otherwise.
Drop-out voltage is 0.35 to 0.55 Uc, and operational range is 0.85 to 1.1 Uc at 55 °C. Heat dissipation runs 18 to 24 W at 50 Hz. Operating time is 20 to 35 ms closing, 7 to 15 ms opening. The asymmetry is normal for an AC coil — the closing time includes the half-cycle delay for the magnetic circuit to build flux. If your application needs faster dropout for arc suppression, factor in the opening delay. The 55 °C ceiling matches the maximum operating rate spec.
