The contactor handles 90 kW at 380-400 V and 100 kW at 415 V in AC-3, which covers most European-standard 400 V motor frames up to that power class. Utilisation categories span AC-3 (squirrel-cage motor starting), AC-4 (plugging/inching), and AC-1 (resistive loads). The AC-4 rating at 33 kW at 400 V is notably lower — if the application requires frequent reversing or inching, that derating matters for contact life. Mechanical durability of 10 Mcycles gives a maintenance planning baseline. The electrical life will be shorter and depends on the switching current and voltage; the AC-3 electrical endurance curve in the TeSys F documentation should be consulted for the specific duty cycle. ## Lifecycle reality — end-of-life sourcing For a BOM freeze or a line-down situation, the procurement path is: submit an RFQ with the quantity and target lead time; availability and pricing are confirmed at quote time. No stock-holding claim is made here — this is a sourced-to-order part. ## Panel integration and mounting constraints Mounting is plate-based, not DIN rail — the contactor bolts to a backplate or mounting plate. The dimensions are 7.1 in (181 mm) deep, 6.6 in (168.5 mm) wide, 6.9 in (174 mm) tall, so it occupies a substantial footprint. Plan for the 25 x 3 mm power circuit bar connection and the 150 mm² lug/ring terminal capacity. Power circuit tightening torque is 159.3 lbf.in (18 N.m) — this is a high-torque connection that needs a torque wrench, not a screwdriver. Control circuit torque is 10.6 lbf.in (1.2 N.m). The IP2X front face with shrouds meets touch-safe requirements per IEC 60529, but only when the shrouds are fitted. Heat dissipation runs 18-24 W total, with 12 W per pole in AC-3 and 25 W per pole in AC-1. In a sealed enclosure, this heat must be factored into the thermal budget — the 3000 m altitude rating without derating assumes free air flow. ## Compliance and documentation Certified to IEC 60947-4-1 and EN 60947-4-1, the relevant product standards for contactors and motor-starters. Also carries JIS C8201-4-1 for Japanese market acceptance. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C — the higher figure applies for clearance/creepage in pollution degree 3 environments. Overvoltage category III means it is suitable for fixed installation downstream of the main distribution board. The protective treatment 'TH' indicates tropicalisation — humidity and fungus resistance for harsh environments. The associated fuse rating is 200 A aM or 315 A gG at <=440 V for short-circuit coordination.","metaTitle":"Schneider Electric LC1F185R6 TeSys F Contactor, 275 A AC-3","metaDescription":"Schneider LC1F185R6 TeSys F contactor, 275 A rated operational current at <=440 V AC-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Contactors"],"specifications":{"Depth":"7.1 in (181 mm)","Range":"TeSys","Width":"6.6 in (168.5 mm)","Height":"6.9 in (174 mm)","Category":"22336-CTR,F-LINE,AC,OPEN,NONREV","Standards":"EN 60947-1 IEC 60947-4-1 JIS C8201-4-1 IEC 60947-1 EN 60947-4-1","Motor power kW":"90 kW at 380...400 V AC 50/60 Hz (AC-3) 100 kW at 415 V AC 50/60 Hz (AC-3) 100 kW at 440 V AC 50/60 Hz (AC-3) 110 kW at 500 V AC 50/60 Hz (AC-3) 110 kW at 660...690 V AC 50/60 Hz (AC-3) 55 kW at 220...230 V AC 50/60 Hz (AC-3) 33 kW at 400 V AC 50/60 Hz (AC-4)","Operating time":"20...35 ms closing 7...15 ms opening","lifecycle_stage":"eol_hot","Heat dissipation":"18...24 W","Mounting Support":"Plate","Range of Product":"TeSys F","Average impedance":"0.33 mOhm - Ith 275 A 50 Hz","Device short name":"LC1F","Poles description":"3P","Tightening torque":"Control circuit 10.6 lbf.in (1.2 N.m) Power circuit 159.3 lbf.in (18 N.m)","Compatibility code":"LC1F","Inrush power in VA":"970 VA, 60 Hz 0.3 68 °F (20 °C))","Operating altitude":"9842.52 ft (3000 m) without derating","Control circuit type":"AC 60 Hz","Overvoltage category":"III","Protective treatment":"TH","Utilisation category":"AC-3 AC-4 AC-1","Contactor application":"Resistive load Motor control","Mechanical durability":"10 Mcycles","Nbr. of units in pkg.":"1","Associated fuse rating":"200 A aM at 315 A gG at <= 440 V","Maximum operating rate":"2400 cyc/h 131 °F (55 °C)","Connections - terminals":"Control circuit screw clamp terminals 1 0.002...0.006 in² (1...4 mm²)flexible without cable end Control circuit screw clamp terminals 2 0.002...0.006 in² (1...4 mm²)flexible without cable end Control circuit screw clamp terminals 1 0.002...0.006 in² (1...4 mm²)flexible with cable end Control circuit screw clamp terminals 2 0.002...0.004 in² (1...2.5 mm²)flexible with cable end Control circuit screw clamp terminals 1 0.002...0.006 in² (1...4 mm²)solid without cable end Control circuit screw clamp terminals 2 0.002...0.006 in² (1...4 mm²)solid without cable end Power circuit bar 2 25 x 3 mm Power circuit lugs-ring terminals 1 0.2 in² (150 mm²) Power circuit connector 1 0.2 in² (150 mm²) Power circuit bolted connection","IP degree of protection":"IP2X front face with shrouds IEC 60529 IP2X front face with shrouds VDE 0106","Rated breaking capacity":"1480 A conforming to IEC 60947-4-1","Product or Component Type":"Contactor","Power dissipation per pole":"12 W AC-3 25 W AC-1","[Uc] control circuit voltage":"440 V AC 60 Hz","[Ui] rated insulation voltage":"1000 V IEC 60947-4-1 1500 V VDE 0110 group C","Control circuit voltage limits":"Operational 0.85...1.1 Uc 50/60 Hz 131 °F (55 °C)) Drop-out 0.35...0.55 Uc 50/60 Hz 131 °F (55 °C))","Power Pole Contact Composition":"3 NO","[Ie] rated operational current":"275 A (at 185 A (at <131 °F (55 °C)) at <= 440 V AC-3","[Ue] rated operational voltage":"<= 690 V AC 50/60 Hz","Hold-in power consumption in VA":"66 VA, 60 Hz 0.3 68 °F (20 °C))","Ambient Air Temperature for Storage":"-76...176 °F (-60...80 °C)","Ambient Air Temperature for Operation":"23...131 °F (-5...55 °C)","[Uimp] rated impulse withstand voltage":"8 kV","[Icw] rated short-time withstand current":"1500 A 104 °F (40 °C) - 10 s 920 A 104 °F (40 °C) - 30 s 740 A 104 °F (40 °C) - 1 min 500 A 104 °F (40 °C) - 3 min 400 A 104 °F (40 °C) - 10 min","[Ith] conventional free air thermal current":"275 A (at 104 °F (40 °C))","Permissible ambient air temperature around the device":"-40...158 °F (-40...70 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$322.58","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.se.com/vn/en/product/LC1F185R6/tesys-f-contactor-3p-3-no-ac3-440-v-275-a-coil-440-v-ac/","alternativesUrl":"https://aoctrl.com/api/mcp/products/LC1F185R6/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LC1F185R6","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/LC1F185R6 when reusing this data.
