Class J Fuse Blocks - Space Saving SJ Series
The Class J Fuse Blocks - Space Saving SJ Series is part of the Mersen (formerly Ferraz Shawmut) fuse holders & blocks line, distributed by Gross Automation.

Ferraz Shawmut expands its popular “SJ” series fuse blocks to now include a 100A version in addition to the existing 30A design. These blocks occupy up to 25% less mounting space than standard Class J fuse blocks. A patented built-in DIN rail adapter on the 30A SJ block adds further design versatility. A choice of box, screw, or pressure plate connectors fit a wide range of stranded, solid copper, or aluminum wire for the 30A design, while the 100A design features a box connector. Insulators are glass-filled polycarbonate with verified dielectric strength in excess of 2500V.
