SYSTEM POWER DEVICES
The requirements for both restricted and non restricted fuses may be meet by using
one of two methods:
•
Use a single fuse that meets all requirements. The easiest way to accomplish this
is to use a “Combination Fuse” from
. These fuses meet all of the
requirements for both Short Circuit Protection and Over Current Protection, and
may be used on Branch Circuits that supply up to 100,000 RMS symetrical short
circuit amperes (480V maximum).
•
Use two fuses connected in series, that, in combination, meet all of the require-
ments:
•
Use an Over Current Protection fuse that has a current rating not greater than
the “Maximum Fuse Size” shown in
, and an interrupt capability not
less than the short circuit rating (Prospective Short-circuit Symetrical
Amperes) of the Branch Circuit supplying the drive.
•
Use a Short circuit Protection fuse (typically a semiconductor fuse) that has a
“Clearance I
2
t” rating not greater than that shown in
, and a current
rating greater than the Over Current Protection fuse (to avoid nuisance trip-
ping).

Kollmorgen.
