A74 gPV 14x51mm Midget Fuse 1500VDC 4~30A 10KA For Electric and Hybrid Electric Vehicles



Midget Fuse A74_datasheet_20170317.pdf





  • 1500 VDC, 14x51mm PV fuse link
  • Rated Current: 4~30A
  • Rated Breaking Capacity: 10 kA
  • Time Constant: ≤1ms
  • Special design with silver plated caps for high-power PV applications
  • Reference Standard:UL 2579/UL248
  • Approvals: UL 2579 Listed(File:E464976)





This A74 series fuse link is designed for circuits requiring gPV type DC fuses in photovoltaic systems up to 1000VDC, in particular against typical cyclical current flow currents as found in photovoltaic applications. Most common usage is in combiner boxes for string protection. It can also serve as alternate protection for high voltage accessories and circuits such as electric and hybrid electric vehicles, Battery protection etc..
