Littelfuse® POWR-GARD® LFJ600303C Non-Indicating Fuse Block, 600 VAC, 30 A, Class: J, 3 Poles

The Littelfuse® 600 VAC 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.

The new Littelfuse® class H and R blocks offer many advantages over previous generations that are noted in the features and benefits section. Class H and class R fuse blocks are dimensionally the same, but class R blocks incorporate A rejection feature, which only allows class R fuses to be inserted.

The all new LLSRK_ID series fuse is the most advanced Class RK1 fuse available today providing unparalleled performance and protection to modern circuits. The patented Indicator™ technology provides instant identification of a blown fuse greatly enhancing system up time, while the precision formed short circuit elements virtually eliminate damage to components from unexpected electrical faults. In addition, the all new solid state overload section has no moving parts, stopping unnecessary fatigue failures commonly found in other spring loaded fuses.
