It's the part that pulls the contactor in and holds it — without a built-in suppressor module, so you'll need to add external suppression (RC snubber or varistor) across the coil terminals if the control circuit drives inductive loads nearby. The coil draws 970 VA inrush at 60 Hz to pull in, then settles to 66 VA hold-in at 60 Hz, cos phi 0.3. That inrush matters for sizing the control transformer — a 100 VA transformer won't cut it if multiple coils pull in simultaneously. ## Key operating parameters Closing time runs 20 to 35 ms; opening is faster at 7 to 15 ms. The coil drops out between 0.35 and 0.55 Uc at 131 °F (55 °C) — so on a 415 V circuit, dropout happens somewhere around 145 to 228 V. Operational range is 0.85 to 1.1 Uc, meaning it reliably picks up from about 353 V up to 456 V. Heat dissipation runs 18 to 24 W at 60 Hz — that's not trivial in a sealed panel; account for it in the thermal budget.","metaTitle":"Schneider LX1FG340 TeSys F contactor coil, 415 V AC 60 Hz","metaDescription":"TeSys F contactor coil LX1FG340, 415 V AC 60 Hz control circuit.
