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 shortcircuit 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.
