UL/CSA Fuse Holders and Accessories

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.

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.

Mersen’s 1500VDC HelioProtection fuse holders for 10/14x85mm gPV fuses introduce the next level of safety for Utility scale photovoltaic applications. The HP15FHM32 fuse holders are also IP20 finger safe, with a rotating fuse carrier like the Mersen UltraSafe® fuse holders. The US15M1HEL fuse holders are finger safe up to an IP20 grade of protection, and feature a pull out, pivoting fuse carrier. All bodies feature high performance UL 94 V-0 rated polymer material, providing superior flammability rating, with exceptional durability and dielectric withstand properties.

The HP15FHM32 series input and output terminals accept standard PV rated wiring and comb bus bars, providing added versatility for end-use installations.The US15M1HEL is designed with terminals to accept standard stock bus bar eliminating the need for custom combed bus bar, saving cost, time and simplifying installation.

Mersen offers an extensive offer of fuse clips.
Clips are made out of spring brass with tin plated finish and match perfectly our selection of fuses. They are designed to mount easily, to save space and provide tight contact.
You can choose from a wide range of traditional and space-saving fuse blocks, fuse clips and fuse holders.

copper designed specifically for 200-600A bladed Class J
fuses.

Mersen UltraSafe™ Fuse Modules have a unique, compact design suited for use with 45mm wide IEC contactors. These modules also offer other features not found on other Class CC and midget UltraSafe fuse holders such as an auxiliary contact option. When the auxiliary is wired to an adjacent contactor the load is dropped out by the contactor immediately once someone tries to open the fuse extractor handle. Additionally, the fuse module features padlock capabilities, compact busbars for line side terminations, and tool free removal from DIN-rail. Yet the fuse modules still incorporate well known UltraSafe features such as IP20 protection, easy operating fuse extraction handles and an open fuse visual indication option.
