It operates on a 55 V AC control circuit at 50/60 Hz, meaning it pulls in the contactor when 55 V AC is applied and drops out when power is removed — standard for panel builders wiring control transformers to a 55 V secondary tap. Rated for 5 Mcycles mechanical durability, this coil will outlast most contactor main poles in normal switching duty — the mechanical life is the limit of the coil plunger and armature, not the electrical contacts. Because this is a coil without a built-in suppressor module, any replacement must account for the external snubber or RC network already in the panel. If you are swapping a failed coil on an existing LX1F contactor, verify the existing suppression arrangement — the LX1FL055 expects the suppressor to be wired externally, not integrated into the coil body. The 55 V AC control voltage is specific — not the common 24 V, 110 V, or 230 V taps. If your control transformer has a 55 V secondary, this coil is a direct fit. If you are sourcing for a panel that uses a different control voltage, this coil will not pull in reliably; the dropout voltage is typically around 70% of rated, so a 55 V coil on a 48 V supply may chatter or fail to seal. Mechanical durability of 5 Mcycles is a solid figure for a coil in this class — it corresponds to roughly 5 million on-off operations before the plunger guide or armature wear out. In practice, the electrical life of the contactor's main poles (which depends on load current and switching frequency) will be the limiting factor in most motor-starting applications.","metaTitle":"Schneider Electric LX1FL055 TeSys Contactor Coil, 55 V AC 50","metaDescription":"Obsolete LX1FL055 TeSys contactor coil from Schneider Electric. 55 V AC 50/60 Hz control circuit, 5 Mcycles mechanical durability.
