Ferraz Shawmut A4J200 200A Class J Fuse – 600V JKS200 JLS200 Replacement NIB

This is a genuine Ferraz Shawmut A4J200, 200 amp, Class J fuse rated at 600 volts.

Still new in box, never used.

It's a direct replacement for JKS200, JLS200, and other Class J applications.

No MPN listed but the A4J200 is the real deal—built tough for industrial panels, switchgear, or heavy machinery.

If you're maintaining old gear or stocking spares, this is the kind of fuse you want when you can't afford a blow-out.

Clean, authentic, and ready to protect your gear.
