250V and 600V 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 250Vac or 600Vac

ratings for conductor sizes from 12AWG to

1000kcmil and terminal options available that

make them easy to install including: tube-

to-tube (crimp), tube-to-bolt (crimp/bolt-in),

compression rod-to-tube (crimp) and bolt-to-

offset bolt (bolt-in) options.

Select cable limiters are UL^®Listed under

•ꢀ

File E90818 for use on 600V circuit for the

protection of faults up to 200kA.

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.

Cable limiters are often used in utility low volt-

age networks and large multi-cable per phase

service entrances.

Unlike fuses, cable limiters are selected by

cable size rather than amperage, 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 of ionized gases or

explosive action.

Under high short-circuit conditions, limiters

cut off fault currents within one-half cycle

(0.008 seconds) 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 to minimize damage to or

eliminate damage to adjacent conductors.
