UL/CSA Fuse Holders and Accessories

Mersen 1SC and 1MSC semiconductor fuse blocks feature modular mounting that offers greater flexibility in adjusting to various fuse lengths. Both stud type and integral box connector versions are offered to allow for user preference of wire terminations. The integral box connector versions also provide for greater heat dissipation. Mounting hardware is supplied with the blocks

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.

Mersen Semiconductor fuse blocks feature open face styles. Each version is rated 750 volts and accommodates 14 x 51mm or 22 x 58mm IEC Cylindrical fuses. 703, U705 and U710 fuseholders feature Mersen's unique adder-block design which can be assembled onto 1, 2, or 3-pole fuseholders to form multi-pole segmented holders of as many poles as desired. A choice of box, screw, or pressure plate connectors is offered to fit a wide range of standard or solid copper wire. All versions have verified dielectric strength in excess of 2500V. A patented built-in DIN-rail adapter on the U710 blocks adds further design versatility. All fuse clips are made of high conductivity tin-plated copper with spring reinforced clips.

Mersen USBB UltraSafe bus bar systems are intended for use with
UltraSafe Class CC (USCC) and Midget (USM) fuse holders. The USBB
delivers safe and reliable combination of circuits in a compact design. Bus
bar systems reduce installation time when compared to wire solutions,
offer space savings and deliver touch-safe, shock resistant solutions to
panel builders and designers. 1-, 2-, and 3-phase designs available.

Mersen P-Block series for Form 101 fuses are glass-filled polycarbonate or laminated phenolic insulator blocks with studs to accommodate bolt-in fuses. All studs, clips and mounting hardware are tin or zinc-plated

The innovative and comprehensive Modulostar® range of Mersen
fuse-holders.
Modular fuse-holders are finger-safe as per IEC standards to an IP20
grade of protection. Including fuse changing, with the flick of a finger.
Modular fuse-holders are available in 1, 2 or 3 poles, with or without
visual blown fuse indicators, in IEC + UL version.
Multi-pole units can also be field assembled by ordering pin-ties
assembly kit. The range offers the possibility to use microswitches
(supplied with the holders or ordered separatly) to allow remote
indication. Modulostar® range is made of tough and durable
thermoplastic or thermoset material.
