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 over-
load protection. Cable limiters are 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 busway
terminal boxes
Large feeders with three or more conductors per phase
FEATURES
s
Current-limiting characteristics provide protection to
conductor insulation and reduce damage when faults occur.
s
Properly applied cable limiters may permit the use of
equipment with reduced withstand ratings
s
Wide variety of terminations and cable ratings permit use
in almost every situation.
