SPECIFICATIONS
Voltage Ratings: 300 Volts AC
600 Volts AC
Ampere Ratings: 0 – 600 amperes
Approvals: UL Listed (File No. E14721)
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.
