Widely used in energy\u2011storage systems, lithium\u2011ion battery\u2011pack protection, DC relay backup protection. aR\u2011class fast\u2011acting characteristic provides reliable short\u2011circuit protection for power semiconductors and DC\u2011side components under heavy fault\u2011current conditions.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Square\u2011body bolt\u2011on mounting; apply correct bolt torque value to avoid poor contact and over\u2011heating risk.<\/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
- Two ordering options: B\u2011version with blow indicator; BN\u2011version without blow indicator, please clarify when placing order.<\/li>\n<\/ul>\n
Packing & Storage Requirements<\/h2>\nStandard original\u2011box bulk package. Store in clean, dust\u2011free warehouse.
