Thank you very much everyone for your quick response. I also found A150X series up to 600A is UL recognized up to 1500VDC with an L/R = 2ms.
Have a happy 4th of July (Independence Day ) and weekend !

When the arc forms, the maximum power in the arc is the rated voltage of the fuse times the rated interrupt current. Both E and I are important for a "safe" (non-explosive) operation. Rich On 7/1/2013 7:20 AM, McInturff, Gary wrote: The voltage rating on a fuse, if I remember correctly, addresses the ability of the voltage source to arc across the gap formed when the fuse ruptures and the 700 V rating would be insufficient in an 840 V circuit.

Hello Intelligent group, The maximum DC bus voltage on our units is 840 VDC. I found UL recognized DC 700 V category fuses and rated current starting from 35 A to 315 A. Could anyone suggest 700 VDC voltage category enough for our 840 VDC units? Thank you.
