Littelfuse LFJ600303CID Class J Fuse Block 30A 600VAC Indicating Bolt-In DIN Rail Phenolic

The LFJ Series by Littelfuse stands out in modern electrical applications with its innovative design and superior functionality. This circuit fuse block features a space-saving architecture that is up to 45% smaller compared to traditional models, allowing for more efficient use of panel space. It is equipped with universal mounting holes for effortless replacement and is conveniently designed for one-handed release from the DIN rail, whether in a lock open or lock closed position. Additionally, all versions—except for those rated 200A-600A—offer visual indication for increased operational awareness. Suitable for Class J fuses, each phenolic block is designed with side barriers for safe isolation, while the spring-reinforced fuse clips ensure reliability in blocks rated at 100A and larger, with optional clips available for lower ratings. This multifaceted fuse block is ideal for meeting diverse application requirements up to 600VAC.
