6.3A Fast Acting 6.3 Amp Ceramic Fuses F6.3AL Cartridge Fuse 5x20mm 250V-10pcs

Bought for back up fuses for generator. Fit and work for emergencies. Cheaper then Generic fuses

The older Generacs used a larger BLS-5 (BBS-5) fuse. The new ones use these. We occasionally manage to pop one when working on a live panel. It's not hard to do that. There are three (N1, N2, and T2 lines), plus Generac gives a spare with the panel, but customers are happier if their electricians replace what they accidentally cooked, so I carry some of these just in case.

Fast delivery of the product i needed

Looks exactly like what I might need if original blows. Hope never to find out but I think I'm ready.

These fit in the 200 amp general transfer switch for utility sensor to start generator

Exactly as described.

Worked exactly the way they should

Great value

Came quick fair price. Have to try on application to see if they work as designed
