Power cabling <strong>vacon</strong> • 284.1.1.2 Cable and fuse sizes, frames MR7 to MR9The recommended fuse types are gG/gL (IEC 60269-1) or class T (UL & CSA). The fuse voltagerating should be selected according to the supply network. The final selection should be madeaccording to local regulations, cable <strong>installation</strong> conditions and cable specification. Bigger fusesthan what is recommended below shall not be used.Check that the fuse operating time is less than 0.4 seconds. Operating time depends on usedfuse type and impedance of the supply circuit. Consult the factory about faster fuses. Vacon offersrecommendations also for high speed J (UL & CSA ), aR (UL recognized, IEC 60269-4) andgS (IEC 60269-4) fuse ranges.FrameTypeI L[A]Fuse(gG/gL)[A]Mains andmotor cableCu [mm 2 ]Terminal cable sizeMain terminalEarthterminal0075 20072 475,072,0803*35+16 (Cu)3*50+16 (Al)6-70 mm 2 Cu/Al 6-70 mm 2MR70088 20087 488,087,0<strong>100</strong>3*35+16 (Cu)3*70+21 (Al)6-70 mm 2 Cu/Al 6-70 mm 20105 20105 4105,0 1253*50+25 (Cu)3*70+21 (Al)6-70 mm 2 Cu/Al 6-70 mm 20140 20140 4140,0 1603*70+35 (Cu)3*95+29 (Al)Bolt size M8Bolt size M8MR80170 20170 4170,0 2003*95+50 (Cu)3*150+41 (Al)Bolt size M8Bolt size M80205 20205 4205,0 2503*120+70 (Cu)3*185+57 (Al)Bolt size M8Bolt size M8MR90261 20261 40310 20310 4261,0 315310,0 3503*185+95 (Cu)Bolt size M8 Bolt size M82*3*120+41 (Al)2*3*95+50 (Cu)Bolt size M8 Bolt size M82*3*120+41 (Al)Table 16. Cable and fuse sizes for Vacon <strong>100</strong>The cable dimensioning is based on the criteria of the International Standard IEC60364-5-52:Cablesmust be PVC-isolated; Max ambient temperature +30°C, max temperature of cable surface +70°C; Useonly cables with concentric copper shield; Max number of parallel cables is 9.When using cables in parallel, NOTE HOWEVER that the requirements of both the cross-sectional areaand the max number of cables must be observed.For important information on the requirements of the earthing conductor, see chapter Earthing andearth fault protection of the standard.For the correction factors for each temperature, see International Standard IEC60364-5-52.24-hour support +358 (0)201 212 575 • Email: <strong>vacon</strong>@<strong>vacon</strong>.com4
