Space saving POWR-GARD Class T fuses are the most compact fuses available in ratings above 30 amperes less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection. For motor and general purpose circuits where space is not critical, we recommend POWR-PRO JTD_ID Indicator series, LLNRK/LLSRK series, or FLSR_ID Indicator series.

The unique design of Littelfuses compact SLC series Class G fuses provide additional time-delay over competitive products which increases system reliability. Compact Class G fuses were the first fuse series to approach midget fuse dimensions and meet NEC requirements for branch-circuit protection. The unique dimensions of SLC series Class G fuses prevents insertion of lower voltage fuses in Class G fuse holders. The fuses varying length prevents insertion of higher ampere rated fuses in fuse holders designed for lower ampere ratings. Class CC fuses are replacing Class G fuses in many new designs. Class CC fuses superior time delay plus higher voltage and interrupting ratings meet the needs of modern circuits. Littelfuses introduction of POWR-PRO CCMR series fuses, with ratings up to 60 Amperes for providing branch circuit protection, are accelerating this trend.

KLSR series RK1 fuses were the earliest type of current-limiting fuse developed. Their single-element, silver link design enables them to provide fast-acting overload and short-circuit protection. When used to protect inductive loads such as motors, solenoids, and transformers, KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLSR series fuses may only provide short-circuit protection. We recommend using POWR-PRO LLNRK/LLSRK series RK1, dual-element, time-delay fuses in all new applications requiring the current-limiting ability of UL Class RK1 fuses, or in existing applications where fast-acting RK1 or RK5 fuses have been opening on harmless system surges such as motor starting currents.
