USCC & USM UltraSafeTM Fuseholders
UltraSafe modular fuseholders for midget and class CC fuses
Mersen UltraSafe Modular Fuseholders introduce a new level of safety for Class CC
(USCC) and Midget 1-1/2” x 13/32” (USM) AC and DC-rated fuses up to 30 amperes.
UltraSafe holders qualify as “Finger-safe” under IEC and DIN standards to an IP20
grade of protection, including fuse changing (with the ick of a nger). UltraSafe
holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators
in each pole. Multi-pole units can also be eld assembled by ordering pin-tie handles.
UltraSafe holders save up to 15% mounting space and any combination can be
snapped onto 35mm DIN-rail for extra savings in panel building time. UltraSafe
holders with Class CC fuses chosen for Type “2” No Damage protection give one of
the safest protection packages in the industry. UltraSafe body material is tough and
durable polyamide, with exceptional insulating properties. Ratings:

USFM UltraSafeTM Fuse Modules
UltraSafe 3-pole fuse modules for midget and class CC 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.

US3J & US6J UltraSafe™ Class J Fuse Holders
UltraSafe™ modular fuse holders for class J fuses
Mersen UltraSafe Modular 600 Volt Fuse Holders for Class J fuses introduce a new
level of safety and ease for installing or replacing Class J fuses. UltraSafe holders
qualify as “nger-safe” to an IP20 grade of protection under IEC standards. The US3J
accommodates 30A Class J or 22 x 58 mm French Ferrule* fuses. The US6J is for
60A Class J fuses. UltraSafe holders are available in compact 1, 2, or 3 pole units,
with or without blown-fuse indicators in each pole. Multi-pole units can also be made
up in the eld by using the multiple-pole Assembly Kits. All units have provisions for
locking in the open position for safety during fuse changeouts or equipment servicing.
US3J and US6J holders can be snap-mounted to 35 mm DIN-rail and they have a
unique latch which will stay open to allow re-positioning of the holder in the future.
UltraSafe body material is tough and durable polyamide.

600 Volt In-Line Fuse Holders
Mersen’s complete line of single and dual pole in-line fuse holders accommodate
either 1-1/2” x 13/32” (10x38mm) 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
eld. Three internal O-rings per pole seal the fuse holder providing a water-resistant
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.

Notes:
1. Non-breakaway units do not include insulator boots. These optional cone shaped boots are available to provide a watertight installation. The insulator boots are
designed to form a watertight seal over conductors, but due to varying wire insulation sizes it is suggested that tape wrap be utilized for best results.
FSB1 = Single conductor boot (used to cover all crimp type & single set screw terminals)
FSB2 = Double conductor boot (used to cover all double set screw (Y-type) terminals)
Insulator boot trimming instructions: Locate wire gage size to be utilized marking on the boot and cut just beneath it.
2. Tightening torque for single and double set screw terminations: 35 lbs.-in.
3. Tightening torque for dual pole fastening screw: 10-15 lbs.-in.
4. FEBN versions have a permanently mounted dummy fuse for neutral applications.

Semiconductor Fuse Holders
750V Semiconductor Fuse Holders
Mersen semiconductor fuse holders feature open face styles. Each version is rated
750 volts and accommodates 14 x 51 mm or 22 x 58 mm fuses. 703, U705 and U710
holders feature Mersen’s unique adder-block design which can be snapped onto 1-,
2-, or 3-pole blocks to form multi-pole segmented blocks of as many poles as desired.
A choice of box, screw or pressure plate connectors is offered to t a wide range of
standard or solid copper wire. All versions have veried dielectric strengths in excess
of 2500V. A patented built-in DIN-rail adapter on the U710 blocks adds further design
versatiltiy. All fuse clips are made of high conductivity tin-plated copper with spring
reinforced clips.

DFC SERIES Dead-Front Fuse Covers
Mersen DFC dead-front fuse covers snap on to individual fuses installed in fuse
blocks, covering exposed live clips and terminals and reducing accidental contact by
personnel. They are sized to t Class G, H, J, K, R, CC or midget fuses for increased
safety and (optional) open-fuse indication. All DFC dead-front fuse covers are
reusable when a fuse is replaced – simply detach from the open fuse and re-attach to
the new replacement fuse. On indicator models an orange indicator light will illuminate
to indicate an open fuse. DFC fuse cover ends can be easily cut to accommodate
existing wiring, safety switches or special installations. A blank label is provided with
each DFC to write in circuit or fuse information.

DFC3M/DFC3LP/DRM
Fuse Block Accessories
DFC3M safety puller protects personnel, covers live parts
The DFC3M safety puller is intended to hold and safely enclose 1-1/2” x 13/32” midget
or Class CC fuses for insertion or removal from fuse clips, making fuse installation
easy and safe without the use of a standard fuse puller. The DFC3M is made of clear
polycarbonate, so the fuse can be identied when installed in a 303 series fuse block.
DFC3LP safety puller holds fuse, protects personnel, and
saves space
The DFC3LP holds and safely encloses 1-1/2” x 13/32” midget or class CC fuse,
similar to the DFC3M, but with a lower prole in height so it takes less room where
space is restricted. The DFC3LP is made of clear polycarbonate so the fuse can be
seen after installation in a fuse block such as the Mersen 303 series.
DRM adapts 303 series midget and class CC fuse blocks to
DIN-rail
The DIN-rail adapter, DRM, provides quick mounting for all Mersen 303 series midget
and class CC fuse blocks to all symmetrical 35mm DIN or asymmetrical 32mm “G”
rail. A DRM adapter is attached to each pole with the screw provided. The DRM is
molded of black polycarbonate and is mounted or dismounted from the rail simply by
depressing the nger pull.
