CSA Certified (File No. LR73091)

RECOMMENDED FUSES

JLLN (300V) and JLLS (600V) series fuses

300 and 600 volt fuse blocks are designed for use with

miniaturized Class T fuses. Class T fuses are very fast-acting,

current limiting, and approximately one-third the size of

electrically-comparable Class RK1 fuses.

FEATURES/BENEFITS

Bases are molded phenolic. To provide a low resistance

connection and long-range reliability, steel reinforcing

springs are supplied as standard. Larger blocks employ an

integral heat sink for maximum heat dissipation.
