It carries a 110 V coil drawing 44 W, breaks up to 6.24 kA Icu, and is certified to IEC 60947, UL, CSA, CE, plus marine approvals including DNV, ABS, and Lloyds. Compared to the TeSys K LC1K09004F7 (20 A, 4-pole, 110 A making capacity), the LC1F780 delivers 780 A switching current and 7800 A rated making capacity, making it the correct choice for high-current motor or resistive loads above 100 A. The LC1F780 is an active TeSys F catalog item; lead time is quoted per RFQ.","metaTitle":"Schneider LC1F780 TeSys F contactor, 780 A, 3-pole, 110 V coil","metaDescription":"Schneider LC1F780 TeSys F contactor: 780 A switching current, 3-pole, 110 V coil, 44 W, 6.24 kA Icu, IEC/UL/CSA/marine certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Depth":"10.04 in (255 mm)","Range":"TeSys","Width":"27.6 in (702 mm)","Height":"17.09 in (434 mm)","Category":"US10I1222336","Standards":"IEC 60947-1 IEC 60947-4-1 EN 60947-1 JIS C8201-4-1 EN 60947-4-1","Product name":"TeSys F","Motor power kW":"450 kW at 1000 V AC 50/60 Hz (AC-3) 400 kW at 380...400 V AC 50/60 Hz (AC-3) 425 kW at 415 V AC 50/60 Hz (AC-3) 425 kW at 440 V AC 50/60 Hz (AC-3) 450 kW at 500 V AC 50/60 Hz (AC-3) 220 kW at 220...240 V AC 50/60 Hz (AC-3) 475 kW at 660...690 V AC 50/60 Hz (AC-3) 110 kW at 400 V AC 50/60 Hz (AC-4)","Operating time":"40...80 ms closing with LX1/LX9 coil 130...230 ms opening with LX1/LX9 coil 70...80 ms closing with LX4 coil 100...130 ms opening with LX4 coil","lifecycle_stage":"eol_hot","Heat dissipation":"22 W","Mounting Support":"Plate","Average impedance":"0.1 mOhm -
