Fuse Holders and Systems

Mersen’s complete line of single and dual pole in-line fuse holders accommodate either 1-1/2" x 13/32" (10 x 38 mm) midget or Class CC fuses. The fuse holders are designed for quick installation. Securing nuts or screws are captive thus speeding installation by reducing the need to locate and assemble loose components in the field. Three internal O-rings per pole seal the fuse holder providing a waterresistant compartment for the fuse. The captive O-rings are colored (blue for single pole and red for dual pole) for quick detection. Optional cone shaped insulator boots can be slipped on to provide a watertight seal (breakaway versions come with boots standard). Both single and dual pole versions have an optional breakaway feature which safely disconnects the load in case of a pole knockdown. Fuses remain safely encapsulated within the watertight fuse holder on the load side. Once the pole has been reinstalled the fuse holder can be easily reconnected.

Mersen Class H, K and R fuse blocks accommodate all Class H, K and R 250 and 600V power fuses. A choice of screw, pressure plate, box and special order stud connectors fit a wide range of stranded or solid copper or aluminum wire. Insulators are either molded glass-filled polycarbonate (GFPC) or phenolic with verified dielectric strength in excess of 2500V. 30, 60 and 100A fuse blocks feature a unique adder block which can be snapped onto 1-, 2- or 3-pole blocks to form multipole segmented blocks of as many poles as desired.
All fuse clips are made of high conductivity tinplated copper, with a choice of spring reinforced or nonspring reinforced clips in 30A and 60A. Clips 100A and above are spring reinforced.

Designed specifically for Mersen’s HP6J and HP10J series of photovoltaic fuses, Mersen’s HPJ fuse holders are certified for use with 90°C temperature rated conductors, an industry first. Fuse holders are available with box connectors, stud connectors or a combination of the two in order to meet various customer requirements. Insulators are either molded glass-filled polycarbonate or phenolic with verified dielectric strength in excess of 2500V. All fuse clips are made of high conductivity tin-plated copper.
