It is a field-replaceable component, not a complete contactor — the coil alone, without a built-in suppressor module, so you will need to add external suppression if the application demands it. Opening time runs 100 to 170 ms; closing time is 40 to 75 ms. Coil resistance measures 72.6 Ω inrush and 1917 Ω holding at 20 °C — the high holding resistance keeps power dissipation low once the contactor is sealed in. The control circuit voltage limits are 0.85 to 1.1 Uc for operation and 0.3 to 0.5 Uc for drop-out, both at 55 °C.","metaTitle":"Schneider Electric LX1FK300 TeSys Contactor Coil, 300 V AC","metaDescription":"Obsolete LX1FK300 TeSys contactor coil, 300 V AC 50/60 Hz.
