The LX1FX048 is a replacement coil for Schneider TeSys F-size contactors, wound for 48 V AC control at 50/60 Hz. That 48 V AC coil voltage is the single spec that decides whether this part matches your existing contactor base — if your panel runs 48 V AC control transformers, this coil drops straight in. The coil carries no built-in suppressor module, so you'll need to add an external RC snubber or varistor across the coil terminals if your PLC output card or relay drives inductive loads; omitting suppression can weld auxiliary contacts or damage the driver.
Durability and operating rate
Rated for 5 million mechanical cycles, which for a coil in a contactor means the armature and return spring are good for the life of most conveyor or pump panels. The maximum operating rate is 600 cycles per hour at 55 °C — that's about 10 operations per minute, enough for frequent start-stop duty on a compressor or fan, but not for high-speed pick-and-place or servo indexing. If your application cycles faster than that, the coil temperature rise will exceed the insulation class; you'd need a larger contactor frame or a reduced-duty cycle.
