Mersen fuse reducers allow the use of lower rated fuses in existing equipment having clips with higher ampere ratings. The use of closer rated time-delay fuses can improve circuit protection. For example, renewable or one-time fuses feeding a motor can be replaced with fuses sized closer to the motor nameplate current. Non-rejection reducers will allow Class H, K or R fuses to fit Class H or K clips. Rejection-type reducers will allow only Class R fuses to fit Class R clips or only Class J fuses to fit Class J clips. Class J fuse reducers are not for bolt on applications. Fuse reducers are sold in pairs unless otherwise noted.

Mersen’s new Generation 2 open style class J fuse blocks accommodate class J fuses ranging from 0-100A, 600V. A choice of screw, pressure plate, and box connectors fit a wide range of stranded or solid wire. Gen2 fuse blocks are DIN-rail mountable, more compact than the traditional offering, and feature dovetail nesting for multipole field assembly. Fuse bases are IP20 rated when paired with Mersen’s newly designed dead front covers.
