It is a field-replaceable component for TeSys D, K, and F contactors — the coil alone, not the full contactor assembly. On the BOM, this is the part you order when the coil fails or you need a different control voltage for an existing contactor base. The 90 V AC coil pulls in at 0.85 to 1.1 times Uc (76.5 to 99 V) and drops out between 0.3 and 0.5 Uc (27 to 45 V). That drop-out margin matters: if your control transformer sags under load, the coil stays sealed until the voltage falls below 27 V, preventing chatter on marginal supply. Opening time runs 100 to 170 ms, closing 40 to 75 ms — fast enough for most motor-starting sequences but not for high-speed jogging circuits. That rate translates to one operation every 1.5 seconds — adequate for conveyor indexing or pump cycling, but not for high-frequency solenoid valves. The coil draws 6 ohms inrush and 134 ohms holding at 20 °C, so the holding current is roughly 0.67 A at 90 V — factor that into your control transformer sizing. This coil ships without a built-in suppressor module. For inductive-load switching on the same control circuit, you will need an external RC snubber or varistor across the coil terminals to protect PLC outputs or relay contacts from the back-EMF spike on dropout. ## Deployment context The coil mounts onto the contactor base in the panel — no DIN-rail space consumed beyond the contactor itself. The 90 V AC control circuit is common in North American 480 V motor control centers where a 480/120 V control transformer feeds the coil; verify your control transformer secondary matches 90 V before specifying.","metaTitle":"TeSys LX1FK090 Contactor Coil, 90 V AC 50/60 Hz","metaDescription":"TeSys LX1FK090 replacement contactor coil. 90 V AC 50/60 Hz control circuit, active production. 10 Mcycles mechanical durability.

There is no pin-compatible alternative with the same 90 V AC rating; the coil form factor is identical across the LX1F series, so swapping voltage requires only the correct coil order code."},{"question":"What compliance documentation is available for the LX1FK090?","answer":"As a current-production Schneider Electric TeSys component, the LX1FK090 is covered by the standard RoHS and REACH declarations for the TeSys range. Specific UL, CSA, or IEC certifications are typically listed on the contactor assembly nameplate rather than the coil alone; verify with the full contactor catalog number for agency markings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LX1FK090","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/LX1FK090 when reusing this data.
