That 26 V is the control voltage — not the main power — so it pulls in the contactor armature when the control circuit energises it. The coil draws 550 VA inrush at 50 Hz (cos φ 0.3) and holds at 45 VA, which tells you the control transformer needs to be sized for the inrush peak, not the sealed VA. Heat dissipation runs 12 to 16 W at 50 Hz; that's the thermal load the enclosure has to shed if the contactor is cycled hard. The coil has no built-in suppressor module, so you'll need to add a flyback diode or RC snubber across the coil terminals if the control circuit drives inductive loads or a PLC output. Without it, the inductive kick when the coil de-energises can couple noise into nearby signal wiring — check the shield first if you see phantom faults on a sensor line sharing the same panel. ## Voltage tolerance and timing The coil picks up reliably between 85% and 110% of Uc (22.1 V to 28.6 V) and drops out between 35% and 55% (9.1 V to 14.3 V) at 55 °C. That dropout margin is wide enough that a sagging 24 V control bus won't cause nuisance dropouts — the coil stays sealed until the bus dips below about 9 V. Closing time is 23 to 35 ms; opening is 5 to 15 ms, fast enough for most motor-starting and interlocking sequences.","metaTitle":"TeSys LX1FF026 Contactor Coil, 26 V AC 50 Hz, Active","metaDescription":"TeSys F LX1FF026 contactor coil, 26 V AC 50 Hz, active production. 12-16 W heat dissipation, 10 Mcycles mechanical durability, no built-in suppressor.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactor & Starter Coils"],"specifications":{"Range":"TeSys","title":"LX1FF026","Category":"22341-CONTACTOR,D,K,&F ACCESS","description":"contactor coil - TeSys F - LX1FF - 26 V AC - 50 Hz","Operating time":"23...35 ms closing 5...15 ms opening","Coil technology":"Without built-in suppressor module","lifecycle_stage":"current","Heat dissipation":"12...16 W 50 Hz","Device short name":"LX1FF","Average resistance":"0.33 Ohm 68 °F (20 °C)","Inrush power in VA":"550 VA 50 Hz cos phi 0.3 (at 68 °F (20 °C))","Control circuit type":"AC 50 Hz","Mechanical durability":"10 Mcycles","Nbr. of units in pkg.":"1","Maximum operating rate":"2400 cyc/h 131 °F (55 °C)","Product or Component Type":"Contactor coil","Inductance of closed circuit":"0.05 H","[Uc] control circuit voltage":"26 V AC 50 Hz","Control circuit voltage limits":"Drop-out 0.35...0.55 Uc 50/60 Hz 131 °F (55 °C)) Operational 0.85...1.1 Uc 50/60 Hz 131 °F (55 °C))","Hold-in power consumption in VA":"45 VA 50 Hz cos phi 0.3 (at 68 °F (20 °C))","Ambient Air Temperature for Operation":"23...131 °F (-5...55 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/e0fbab592be7e783de1e22a8e41b812a.pdf","sourceUrl":"https://www.se.com/vn/en/product/LX1FF026/contactor-coil-tesys-f-lx1ff-26-v-ac-50-hz/"},"ai":{"faq":[{"question":"What is the TeSys range for this coil?","answer":"The LX1FF026 belongs to the TeSys F range of contactor coils, designed for use with TeSys F contactors."},{"question":"What is the category for LX1FF026?","answer":"The category is 22341-CONTACTOR,D,K,&F ACCESS, which covers contactor accessories for the D, K, and F ranges."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LX1FF026","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/LX1FF026 when reusing this data.
