It's the part you swap when a coil opens or shorts on a TeSys F frame — no suppressor module built in, so you add external flyback suppression if the circuit needs it. The 68 V AC coil pulls 550 VA inrush at 20°C (cos φ 0.3) and settles to 45 VA holding, dissipating 12-16 W. That inrush matters for transformer sizing on the control bus — a 100 VA control transformer won't hold two of these closing simultaneously. ## Voltage tolerance and timing Drop-out range is 0.35 to 0.55 Uc at 55°C — so the coil releases between roughly 24 and 37 V AC. Operational pickup is 0.85 to 1.1 Uc, meaning it needs at least 58 V AC to pull in reliably at temperature. Closing time runs 23-35 ms, opening 5-15 ms.","metaTitle":"Schneider Electric LX1FF068 TeSys F Contactor Coil, 68 V AC","metaDescription":"Active TeSys F contactor coil, 68 V AC 50 Hz control voltage. 550 VA inrush, 12-16 W holding dissipation. 10 Mcycles mechanical life.
