    Application Scenarios<\/h2>\n

    GFBFG4\u2011S\u2011105ES Series Square\u2011Body aR ESS DC Power Fuse 1500VDC 400\u20112000A is designed for heavy\u2011duty new\u2011energy industrial DC projects. Mainly used for large\u2011scale industrial energy\u2011storage systems and wind\u2011power converter cabinets. aR\u2011class partial\u2011range protection characteristic delivers reliable short\u2011circuit protection for power semiconductors and high\u2011power DC equipment under severe fault\u2011current conditions.<\/p>\n

    Installation & Operating Notes<\/h2>\n
      \n
    • #4 square\u2011body with two M12 mounting holes; apply correct bolt torque value to avoid poor contact and over\u2011heating risk; terminal tin\u2011plated 3\u20115\u03bcm surface treatment.<\/li>\n
    • Recommended continuous operating current \u226475% of fuse rated\u2011current; apply temperature\u2011derating\u2011factor Kt for ambient temperature over 40\u2103.<\/li>\n
    • Altitude \u22642000m no\u2011derating; closed\u2011box installation 2000\u20114500m: derate 2%\u20115% rated\u2011current per 1000m elevation increase. Open\u2011air installation can normally ignore altitude influence. Re\u2011check insulation clearance at high altitude per GB\/T16935.1.<\/li>\n
    • Supports vertical, horizontal and inclined mounting; avoid gravity\u2011vibration adverse impact for spring\u2011contact construction.<\/li>\n
    • Forced\u2011air cooling can improve heat dissipation and increase allowable operating current, refer to Kv correction coefficient.<\/li>\n
    • Do NOT replace fuse under live DC load unless equipped with certified load\u2011break switchgear.<\/li>\n
    • Replace fuse immediately if mechanical damage, crack or deformation occurs on fuse body.<\/li>\n
    • Additional reliability validation test shall be conducted for extremely high\u2011vibration industrial working environments.<\/li>\n
    • Select matched copper conductor cross\u2011section for terminals to control temperature\u2011rise performance.<\/li>\n
    • *Note: Model marked asterisk, please confirm with factory before ordering.<\/li>\n<\/ul>\n
