700 Vac JKS-700 fast-acting fuses

Catalog symbol:JKS-_-700

Description:

  • The JKS-700 is a fast-acting, current-limiting fuse that is UL Recognized and has CSA Component Acceptance for applications up to 700 Vac.

            The JKS-700 is available in ratings up to 60 amps with the same dimensions as a standard Class J fuses; but its voltage rating places it outside

            the standard Class J fuse class. The timecurrent curves shown for the 600 Vac fuses apply to the 700 Vac versions, but the current let-through

            curves do not ..

  • Bussmann recommends the JM70100 modular fuse block and the JM70100-MW power distribution fuse block for the 30 amp case sizeJKS-700 fuses.
