1 class T FuseBlocks NEW! Smaller Design Description The new Littelfuse Class T fuse blocks offer many advantages over previous generations that are noted in the features and benets section. Of particular value is the space savings these new blocks provide. Features/Benets Compact design means increased space savings DIN Rail releasable for all 30 A-60 A fuse blocks Only one hand is required to release from DIN Rail (lock open lock closed) Molded phenolic base Ordering Information (Class T 300 V) Steel reinforcing springs supplied as standard in order to provide low resistance connection and long-range reliability Larger blocks employ integral heat sink for maximum heat dissipation Universal mounting holes make for easy replacement Specications Voltage Ratings: Ampere Ratings: Leakage Current: 300 VAC/600 VAC A <0.6 ma at 600 V Flammability Rating: UL94 V-0 Approvals: UL Listed (File No. E14721) CSA Certied (File No. LR73091) Recommended Fuses 300 V: JLLN 600 V: JLLS 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 fuse.
