The L25S series is a traditional North American bolted-style, high-speed fuse designed with POWR-SPEED® technology for protection of power semiconductor devices that are rated up to 250 V ac and up to 200 V dc. This is a round body, extremely...

Littelfuse SLC fuses provide cost effective branch circuit protection. Fuse length varies to prevent over-fusing. Compact Class G fuses were the first fuse series to approach midget fuse dimensions and meet NEC® requirements for branch-circuit protection.

The L15S series is a traditional North American bolted-style, high-speed fuse designed with POWR-SPEED® technology for protection of power semiconductor devices that are rated up to 150 V ac and up to 150 V dc. This is a round body, extremely...

The FLNR series sets the standard for general purpose fuses. The dual-element design provides advanced short-circuit and overload protection. These time-delay fuses are also available in an indicating version, see FLNR_ID series.

The BLS series fast-acting fuses are 13 ⁄8" long in comparison to other midget fuses, which are 1½" long. They provide space-saving, low-cost protection for street lighting, metering, control and electronic circuits. These fuses open circuits quickly...

KLDR Series time-delay fuses are designed to protect control transformers, solenoids, and similar inductive components with high-magnetizing currents during the first half-cycle. These small-sized fuses provide excellent protection of motor branch...

The FLSR_ID Indicator™ Series offers a patented, state-of-the-art, solid-state design with maximum reliability and superior performance characteristics. The dual-element design ensures advanced short-circuit and overload protection. This series offers...

The 202 series is a three-phase, auto-ranging, dual-range voltage monitor that protects 190–480 V ac, 50*/60 Hz motors regardless of size. The 202-RP (and the 202-575-RP for 475–600 V ac) monitors the phase rotation of the three-phase systems and trips...

Littelfuse LLNRK and LLSRK series POWR-PRO™ fuses provide superior overload and short circuit protection for service entrance, main, feeder and general-purpose branch circuits up to 600 amperes.

The BLN series 250 V ac fast-acting fuses provide low-cost overcurrent protection for military applications and control circuits. They supplement the primary branch-circuit fuse or breaker to provide additional backup protection. These fuses also have...

KLDR Series time-delay fuses are designed to protect control transformers, solenoids, and similar inductive components with high-magnetizing currents during the first half-cycle. These small-sized fuses provide excellent protection of motor branch...

The ARP Series is used in systems where equal run time for two motors is desirable. The selector switch allows selection of alternation of either load for continuous operation. LED’s indicate the status of the output relay. This versatile series may be...

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,...

The FLSR series dual-element, time-delay UL Class RK5 fuses are the most widely used fuse class. They offer superior performance and excellent protection for all types of circuits, especially those with motors. Precision manufactured parts ensure an...
