Control voltage limits are 0.85...1.1 Uc for operation and 0.3...0.5 Uc for drop-out at 131 °F (55 °C). That means the coil holds in down to about 637 V AC and drops out reliably below 375 V AC — useful for brownout ride-through or for verifying the coil will release on a sagging line. For a coil that cycles continuously — say, a conveyor jog or a reciprocating compressor — that rate sets the upper bound before thermal buildup shortens life. Coil resistance is 357 ohms inrush and 8735 ohms holding at 68 °F (20 °C). The high holding resistance means low steady-state power dissipation once the contactor is sealed — the inrush current is brief, so the coil runs cool in continuous duty. This coil has no built-in suppressor module. If the contactor is driven by a PLC output or a solid-state relay, an external RC snubber or varistor across the coil terminals is needed to limit voltage spikes on dropout. The LX1FK750 is a replacement or spare coil for TeSys F contactors in motor control centers and panel builds. The 750 V AC control voltage is common in North American 600 V class installations and some European 690 V networks, so it fits plants with higher control voltages.","metaTitle":"Schneider Electric LX1FK750 TeSys Contactor Coil, 750 V AC","metaDescription":"Schneider Electric LX1FK750 TeSys contactor coil, 750 V AC 50/60 Hz, active production.
