It is not a complete contactor — it is the coil assembly that mounts onto the FK-style contactor frame. The operating time is 40 to 50 ms for opening and 60 to 70 ms for closing, which matters when sequencing contactors in a motor starter or reversing circuit where timing overlap must be controlled. ## Control voltage and coil limits Rated for 45 V DC control voltage, this coil drops out between 0.2 and 0.35 Uc (9 to 15.75 V DC) and operates reliably from 0.85 to 1.1 Uc (38.25 to 49.5 V DC) at 55 °C. If your control supply sags below 38 V DC under load, the contactor may drop out unexpectedly — verify your DC bus regulation, especially in long cable runs or shared power supplies. The coil ships without a built-in suppressor module, so you must add a freewheeling diode or RC snubber across the coil terminals to protect the PLC output or relay driving it. ## Operating temperature range Rated for ambient air operation from -5 to 55 °C (23 to 131 °F). If your panel ambient exceeds 55 °C, this coil is not suitable without derating or forced cooling.","metaTitle":"Schneider TeSys LX4FL045 Contactor Coil, 45 V DC","metaDescription":"Schneider TeSys LX4FL045 contactor coil, 45 V DC control voltage, active production.

There is no pin-compatible 45 V DC alternative listed in the same series — the voltage is specific. If your control voltage is flexible, a standard 48 V DC TeSys FK coil may work within tolerance, but verify the drop-out and operational limits against your supply."},{"question":"What compliance documentation is available for the LX4FL045?","answer":"As a Schneider TeSys component, the LX4FL045 falls under the standard RoHS and REACH compliance declarations for the TeSys range. Specific UL or IEC certifications for the coil are typically covered under the contactor assembly listing; the coil itself is a replacement part. Request the manufacturer's declaration of conformity from your distributor for audit documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LX4FL045","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LX4FL045 when reusing this data.
