Suitable for new\u2011energy vehicle on\u2011board circuits, energy\u2011storage power\u2011station cabinets, lithium\u2011ion battery\u2011pack protection and DC relay backup short\u2011circuit protection. aR\u2011class fast\u2011acting performance delivers reliable fault\u2011current protection for power semiconductors and high\u2011power DC\u2011side power components.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Size 2# square\u2011body; select B\u2011flat bolted horizontal or K\u2011hook\u2011fork vertical terminal version according to cabinet layout; apply specified bolt torque 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 above 40\u2103.<\/li>\n
- Altitude \u22642000m no\u2011derating; closed\u2011box installation between 2000\u20114500m: derate 2%\u20115% rated\u2011current per 1000m elevation increase. Open\u2011air installation normally ignores altitude impact. Re\u2011check insulation clearance at high altitude in compliance with GB\/T16935.1.<\/li>\n
- Supports vertical, horizontal and inclined mounting; prevent gravity\u2011vibration negative influence over electrical contact performance for spring\u2011contact\u2011type devices.<\/li>\n
- Forced\u2011air cooling improves heat dissipation and increases 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 shell crack, deformation or mechanical damage appears.<\/li>\n
- Additional reliability validation test required for extremely high\u2011vibration EV and industrial environments.<\/li>\n
- Select matched copper conductor cross\u2011section for terminals to control temperature\u2011rise performance.<\/li>\n
- Ordering note: clarify terminal type B(flat bolted) or K(hook\u2011fork customized) when placing purchase order; electrical performance is identical for two terminal versions.<\/li>\n<\/ul>\n

REACH declaration available upon customer request.<\/p>\n FAQ<\/h2>\nQ: What rating for GFEVT1500\u201159E Series Square\u2011Body Fast\u2011Acting aR DC Fuse 1500VDC 100\u2011400A?<\/strong>
\nA: Rated 1500VDC, current range 100\u2011400A, aR fast\u2011acting class, max breaking capacity 250kA@1500VDC(Time Constant \u22645ms), minimum breaking current \u22655In, Size 2# 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 GFEVT1500\u201159E?<\/strong>
\nA: Size 2# square\u2011body construction, two optional terminal structures B \/ K.<\/p>\nQ: What standards does GFEVT1500\u201159E 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 GFEVT1500\u201159E?<\/strong>
\nA: New\u2011energy vehicle on\u2011board circuits, energy\u2011storage cabinets, lithium\u2011ion battery\u2011pack and DC relay backup short\u2011circuit protection.<\/p>","protected":false},"excerpt":{"rendered":"GFEVT1500\u201159E square\u2011body fast\u2011acting aR DC fuse,1500VDC 100\u2011400A,250kA breaking capacity.
