Suitable for large\u2011capacity energy\u2011storage power\u2011station cabinets, lithium\u2011ion battery\u2011pack protection, maintenance safety disconnect switches and DC relay backup short\u2011circuit protection. aR\u2011class fast\u2011acting performance delivers reliable fault\u2011current protection for power semiconductors and high\u2011voltage DC\u2011side power components.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Size 3# square\u2011body construction; select B\u2011flat bolted or K\u2011hook\u2011fork terminal according to cabinet layout. Apply proper bolt torque to prevent bad contact and over\u2011heating.<\/li>\n
- Recommended continuous working current \u226475% of fuse rated\u2011current. Apply temperature\u2011derating factor Kt when ambient temperature exceeds +40\u2103.<\/li>\n
- Altitude \u22642000m: no\u2011derating; closed\u2011box installation 2000\u20114500m: derate 2%\u20115% per 1000m elevation. Re\u2011check insulation clearance per GB\/T16935.1 for high\u2011altitude deployment under 1500VDC high\u2011voltage condition.<\/li>\n
- Permits vertical, horizontal, inclined mounting. Avoid gravity\u2011vibration negative influence over electrical contact performance.<\/li>\n
- Forced\u2011air cooling improves heat dissipation and allowable operating current, refer to Kv correction coefficient.<\/li>\n
- Never replace fuse under live DC load unless equipped with certified load\u2011break switchgear, strictly follow 1500VDC high\u2011voltage safety operation procedure.<\/li>\n
- Replace fuse immediately if shell crack, deformation or mechanical damage appears.<\/li>\n
- Additional reliability validation test required for extremely high\u2011vibration industrial environments.<\/li>\n
- Select matched copper conductor cross\u2011section for terminals to control temperature\u2011rise performance for high\u2011voltage heavy\u2011current working condition.<\/li>\n
- Ordering reminder: specify terminal type B(flat bolted) or K(hook\u2011fork customized) when placing purchase order; models marked asterisk * need factory pre\u2011confirmation before order placement, electrical performance is identical for two terminal versions.<\/li>\n<\/ul>\n
Packing & Storage Requirements<\/h2>\nStandard original\u2011box bulk package. Store in clean, dust\u2011free warehouse. Storage temperature:\u201140\u2103~+120\u2103; humidity limit: RH\u226470%@40\u2103, RH\u226480%@30\u2103, RH\u226490%@20\u2103. Sample testing support, OEM customization, stable mass\u2011volume supply for energy\u2011storage and new\u2011energy equipment manufacturers. REACH declaration available upon customer request.<\/p>\n FAQ<\/h2>\nQ: What rating for GFHVT1500\u201174ES Series Square\u2011Body Fast\u2011Acting aR DC Fuse 1500VDC 100\u2011800A?<\/strong>
\nA: Rated 1500VDC, current range 100\u2011800A, aR fast\u2011acting class, max breaking capacity 50kA@1500VDC(Time Constant \u22645ms), minimum breaking current \u22655In, Size 3# square\u2011body.<\/p>\nQ: Difference between B\u2011type and K\u2011type terminals?<\/strong>
\nA: B\u2011type is flat bolted horizontal connection; K\u2011type is customized hook\u2011fork vertical terminal. Both versions share exactly same electrical parameters, only mechanical mounting differs, specify terminal model on purchase order.<\/p>\nQ: What body size for GFHVT1500\u201174ES?<\/strong>
\nA: Size 3# square\u2011body construction, two optional terminal structures B \/ K.<\/p>\nQ: What standards does GFHVT1500\u201174ES comply with?<\/strong>
\nA: Performance referenced to UL\u2011248\u20111\/UL\u2011248\u201113, IEC60269\u20111\/IEC 60269\u20114, RoHS compliant; REACH document available on request.<\/p>\nQ: Main application scenarios for GFHVT1500\u201174ES?<\/strong>
