Blocks and Holders
In-Line Watertight Fuseholders
LEB/LEC
One-pole LEB and LEC Fuseholders
Basic single-pole LEB and LEC watertight fuseholders provide
protection for a variety of circuits. LEB fuseholders accept all
13 / 32 ” x 1 1 / 2 ” midget fuses providing supplemental overcurrent
protection. LEC fuseholders are UL Listed Class CC fuseholders
which accept only Class CC fuses and meet National Electrical Code
requirements for branch circuit protection. The most common use for
either fuseholder is for protection of lighting circuits. However, consider
them wherever there is a need for secure in-line protection, from boat
circuits to electric wheelchairs. Great flexibility is achieved when the
basic holders are combined with breakaway receptacles, Y-terminals
and insulating boots.
LEX/LEY
Two-pole LEX and LEY Fuseholders
LEX and LEY fuseholders are intended for use on line-to-line circuits up
to 600 volts and are ideal for line-to-line loads such as 240 or 480 volt
ballasts. When the line and load sections of LEX and LEY fuseholders
are separated, or when the fuseholder is removed from a two-pole
breakaway receptacle, both lines are disconnected simultaneously. This
prevents the possibility of shock from backfeeding through an exposed
fuse, which could happen with single-pole fuseholders. The LEX holder
is a two-pole version of the LEB and accepts midget fuses, providing
supplementary overcurrent protection. The LEY holder is a two-pole
LET
Breakaway
version of the LEC, which accepts only Class CC fuses, and may be
used to provide branch circuit protection. Both fuseholders may be
equipped with Y-terminals, breakaway receptacles and insulating boots.
One-pole LET Solid Neutral Disconnects
The LET solid neutral disconnect is designed for use as a no-load
non-fused disconnect. Similar in design to the LEB series fuseholders,
the LET is easily identified by its all white body. Internally, it has
a permanently installed solid tin-plated copper neutral slug which
eliminates the possibility of placing a fuse in the neutral side of the
circuit. Fusing the neutral side causes a safety hazard and also violates
the National Electrical Code. The LET is available in both breakaway and
non-breakaway configurations with a wide variety of terminations.
Breakaway Feature
Littelfuse LEB, LEC, and LET single-pole fuseholders and LEX and LEY
two-pole fuseholders are available with an optional breakaway feature
required to meet state and federal highway commission standards
requiring fuseholders to readily disconnect from the line in case of
a pole knockdown. The breakaway feature consists of a receptacle
permanently attached to the power line and a fuseholder with matching
terminals. When knockdown occurs, the parts separate readily. The
breakaway receptacle terminal is deeply recessed so that energized
parts are not exposed. The fuse remains safely enclosed inside the now
de-energized watertight fuseholder. After the pole has been reinstalled,
the fuseholder is easily plugged into the receptacle, immediately
restoring service. The breakaway feature may also be used in marinas,
travel trailer parks and other locations where circuits subjected to strain
must be safely disconnected.
