The Littelfuse 600 V Class J blocks offer generous space savings and enhanced value over previous generations, such as indication, snap-to-release DIN-rail mounting and universal mounting holes.

Littelfuse DIN series midget fuse blocks have integral DIN rail mounting capabilities that allow secure mounting to 35mm DIN rails. New releasable mechanism allows installation and removal of block without removing adjacent components on DIN rail. Electrical panel builders and machine builders no longer need to use mounting adapters, saving assembly time and related costs.

Features and Benefits: Indication offered on all versions except 200A-600A. DIN Rail releasable for all non-knife blade style fuses. Only one hand is required to release from DIN Rail (lock open lock closed). Phenolic blocks have side barriers for isolation. Spring reinforced fuse clips are standard on 100A and larger blocks. Reinforcing springs are optional on 30A and 60A blocks. Universal mounting holes make for easy replacement. Space-saving design — up to 45% smaller than existing blocks.

Safe distribution of power to multiple fuse holders in a compact design is a key objective for panel designers. The Littelfuse UL508 bus bar system eliminates most wire terminations in a time saving package. A power distribution block and associated conductors are no longer needed to feed multiple POWR-SAFE™ fuse holders. Features/Benefits: Decreases wiring terminations; Small footprint reduces space requirements; Reduces assembly time; Prevents accidental finger exposure; Quick and safe method of changing fuse holder configurations; Allows for future expansion; Improves troubleshooting; Eliminates power distribution block; RoHS compliant and lead (Pb) free. Customization: This product is simple to integrate into one- and three-phase applications. It offers multiple pole configurations and amperage ratings to match the designer’s requirements. Instructions are included for bus bar cutting by the customer for further customization. Individual power feed lugs are available which allow termination at any point along the bus bar.

POWR-BLOKS power distribution blocks offer a safe, convenient way of splicing cables, providing a fixed junction tap-off point or splitting primary power into secondary circuits. LX2XXX-DIN series offers integral DIN-Rail mount and an optional hinged safety cover. Applications: Typical applications include heating, air conditioning and refrigeration systems, elevator systems, material handling equipment, control panels, motor controls, switchgear, and anywhere power needs to be distributed to more than one load.

The Littelfuse LFPSC fuse holder is designed to hold Class CC fuses. Features/Benefits: Finger-Safe design offers personnel protection; Compact design; 35 mm DIN Rail Mountable; No fuse pullers or tools required for fuse removal; Indication option available.

Littelfuse LSCR Series is a comprehensive line of modular fuse blocks, designed to accommodate a wide range of High-Speed and UL Power Fuses. These LSCR Series blocks have modular stud type design that enables easy mounting in panel boards. LSCR Series blocks are CE Certified and RoHS Compliant. Features and Benefits: Modular design reduces inventory requirements; Sold in pairs for convenience; Supplied with nut and belleville washer; Constructed of molded phenolic (with plated steel studs) provide greater heat dissapation.
