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.
