LFCL CABLE LIMITERS
250/600 VAC
Description
Cable limiters are fusible devices that provide very fast short-
circuit protection, primarily to faulted cables, but also to other
conductors such as busway. Cable limiters do not have an
ampere rating, and cannot be used to provide overload protection.
They are instead selected by cable size; for example, a 500 kcmil
cable requires a 500 kcmil cable limiter. Their main use is to
isolate faulted cables in circuits containing three or more parallel
conductors per phase. They may be installed on the line side of
the main service to provide short-circuit protection to the service
conductors. This is especially important when service conductors
are tapped from large low voltage networks or from large low
impedance transformers.
Cable limiters have terminals which permit them to be installed in a
variety of equipment. The most common configuration is the offset
blade on one end and the crimp terminal on the other end. This
permits the limiter to replace a cable terminal (lug).

Applications
• Service Entrance Conductors
• Between Transformer or network bus and bus-way terminal
boxes as secondary ties.
• Feeders with three or more conductors per phase to share
heavier load in large commercial and industrial installations
• Multiple Single conductor services, tapped from single
(utility) transformer in multi-family residential and small
commercial installations.

Features
• Current-limiting characteristics provide protection to conductor
insulation and reduce damage when faults occur.
• Properly applied cable limiters may permit the use of
equipment with reduced withstand ratings
• Wide variety of terminations and cable ratings permit use in
almost every situation.
