Fuse saving

(OP)
What fuse types coordinate well with lateral fuse saving recloser trip curves?


Thanks!

RE: Fuse saving

Big ones - but not too big. looking around. It's not so much the type as it is the fuse size. Below a certain size fuse, fuse saving will not be perfect, especially if available fault currents are high. If you look at the relcoser's fast and slow curves, you'll be able to find a range of fuses where it may work. The fuse curve needs to basically be in between the fast and slow curves. We generally recommend "T" links as the best all-around choice for fuse links.

Generally, how many times higher should a fuse rating be compared to the maximum anticipated load? Will fast blow fuses like type a K work better or slower blow like type QT?
