It operates on a 36 V AC 50 Hz control circuit, drawing 550 VA inrush power at 68 °F (20 °C) with a 0.3 power factor, then holding in at 45 VA under the same conditions. Closing time runs 23 to 35 ms, opening 5 to 15 ms, which is standard for this contactor frame size. The 36 V AC control voltage must match the existing control transformer or circuit — this coil will not pull in on 24 V or 48 V. The drop-out threshold is 0.35 to 0.55 Uc (about 12.6 to 19.8 V), and the operational range is 0.85 to 1.1 Uc (30.6 to 39.6 V) at 131 °F (55 °C). If your control supply sags below 30.6 V during inrush, the coil may chatter or fail to close. Heat dissipation is 12 to 16 W at 50 Hz, so the enclosure must allow that thermal load to escape, particularly if multiple contactors are ganged. This part is classified as obsolete by the manufacturer. If you are qualifying a replacement for a new design, expect to evaluate a different TeSys F coil with the same mounting footprint and a 36 V AC rating, but verify the coil resistance and inrush profile against the contactor's minimum pick-up voltage. ## Integration notes for panel builders The coil has no built-in suppressor module, so you must add an external RC snubber or varistor across the coil terminals if the control circuit drives PLC outputs or solid-state relays — otherwise the inductive kick during de-energization can damage downstream electronics. Average coil resistance is 0.63 Ω at 68 °F (20 °C); inductance of the closed circuit is 0.09 H.","metaTitle":"Schneider Electric LX1FF036 TeSys F Contactor Coil, 36 V AC","metaDescription":"LX1FF036 TeSys F contactor coil from Schneider Electric. 36 V AC 50 Hz control circuit, 550 VA inrush, 10 Mcycles mechanical durability.
