250 V and 600 V cable limiters

Features and benefits:

•

Cable limiters enhance multi-conductor system

reliability by isolating faulted conductors and

taking them offline while the balance of the

conductors continue delivering power to their

circuits. This is why cable limiters are often

used in utility low voltage networks and large

multi-cable per phase service entrances.

•

Cable limiters enhance service entrance

conductor short-circuit protection with current-

limiting performance that exceed the typical

protection offered by utility overcurrent

protective devices.

Cable limiters meet many system requirements

with 250 Vac or 600 Vac ratings for conductor

sizes from 12 AWG to 1000 kcmil and terminal

options available that make them easy to install

including:

•

Tube-to-tube (crimp)

Tube-to-offset bolt (crimp/bolt-in)

Tube-to-center bolt (crimp/bolt-in)

Compression rod-to-tube (crimp)

Bolt-to-offset bolt (bolt-in)

Product description:

Cable limiters are intended to provide short-circuit

protection to electrical systems, typically between

the transformer and service entrance. Should a

short-circuit occur, the cable limiter removes the

affected cable(s) from service and permits the

other conductors to continue delivering power.

•

Select cable limiters are UL Listed under File

E90818 for use on 600 V circuit for protection

against faults up to 200 kA.

Cable limiters are often used in utility low voltage

networks and large multi-cable per phase service

entrances.

Unlike fuses, cable limiters are selected by cable

size rather than amp rating, e.g., a “4/0” limiter

will carry the current of a 4/0 cable.

Limiters are stable, totally self-contained, static

devices with unchanging characteristics that

operate without venting ionized gases or explosive

action.

Under high short-circuit conditions, limiters cut off

fault currents within one-half cycle (0.008 second)

and reduce insulation damage from the immense

heat that is developed by sustained fault current

flow. They confine damage to the point of the

short-circuit and stop long-length cable burn-back

and striking of multiple arcs. This minimizes or

eliminates damage to adjacent conductors.
