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
