Im trying to spec a 12.47kV load break switch with a 600A fuse, or close to it. Finding the 600A switch is easy but I cant seem to find a 600A fuse/fuse holder. Only 540A but requires 800A holder, what am I missing?
Still havent entirely resolved this issue. Even with double barrel fuses I cannot seem to get a 600A fuse within a 600A switch. I've checked schnider ele and square D with no luck..
The bus in your switchgear can be manufactured or modified as necessary to accomadate the RBA-800 fuse mounts.
The price of the fuses gets rather expensive. I have seen eurpean DIN size fuses used frequently due to lower costs. Using a vacuum breaker with protection relay may not be that much more cost wise compared with a set of RBA-800's, mounting parts and a set of spare fuse links.
Like alehman said, consult with the eaton rep and local regulations and codes first.
yeah, Im going to get a quote for a sf6 switch vs. fuses. I need to find the number for an actual technical sales rep for some suppliers. I can only seem to find local low voltage reps and online (useless) run-around numbers.
