It's a low-consumption coil — meaning it draws 690 to 855 VA inrush and only 6.6 to 8.1 VA holding — sized for continuous duty in a panel. The coil's operating time is 130 ms opening and 35 ms closing, which is standard for this frame size. The coil is rated for 280 V AC control voltage, with an operational range of 0.85 to 1.1 Uc (238 to 308 V AC) at 131 °F (55 °C). Drop-out occurs between 0.2 and 0.55 Uc (56 to 154 V AC) — so if your control voltage sags below that threshold, the contactor will drop out. That's important for brownout-prone sites. Average coil resistance is 91.33 ohms inrush and 3368 ohms holding at 68 °F (20 °C). The closed-circuit inductance is 14 H. Heat dissipation runs 5.9 to 7.2 W — modest for a contactor coil this size, but worth checking against your panel's thermal budget if it's densely packed. This coil uses AC low-consumption technology without a built-in suppressor module. If your control circuit requires surge suppression (for PLC outputs or sensitive electronics), you'll need to add an external RC snubber or varistor across the coil terminals. The LX9FF designation identifies this as a specific contactor coil for the TeSys F contactor series. The TeSys F range covers motor starters and contactors from about 9 to 38 A in AC-3 duty. This coil is the 280 V AC variant — other voltages in the LX9FF family cover 110 V, 220 V, 380 V, and 415 V AC. The coil is a service part, not a standalone contactor; it mounts onto the contactor's magnet assembly.","metaTitle":"TeSys LX9FF280 Contactor Coil, 280 V AC, Obsolete","metaDescription":"TeSys F specific contactor coil LX9FF280, 280 V AC 40-400 Hz low consumption.
