Mersen is excited to introduce our next generation Open Style Class J Fuse Blocks with newly designed dead front covers.

Mersen’s new Gen2 fuse blocks offer market-relevant features at a competitive price to meet our customers’ application and commercial demands for quick and easy multi-pole field assembly. Our Gen2 Open Style Class J Fuse Blocks accommodate Class J fuses ranging from 0-100A, 600V. The Gen2 fuse blocks are available with a choice of screw, pressure plate, and box connectors to fit a wide range of stranded or solid wire. Gen2 fuse blocks are now DIN-rail mountable, more compact than the traditional offering, and feature dovetail nesting.

Mersen’s newly designed dead front covers are transparent to facilitate easy viewing of fuses. Fuse blocks are IP20 rated when paired with the new dead front covers, and also feature a lock-out tag-out feature for safety.
