can be installed with either input fuses or an input

circuit breaker. Local/national electrical codes may determine addi-
tional requirements for these installations.

The tables on the following pages provide drive ratings and recom-
mended AC line input fuse and circuit breaker information. Both
types of short circuit protection are acceptable for UL and IEC
requirements. Sizes listed are the recommended sizes based on 40
degree C and the U.S. N.E.C. Other country, state or local codes may
require different ratings.

Fusing

If fuses are chosen as the desired protection method, refer to the
recommended types listed below. If available amp ratings do not
match the tables provided, the closest fuse rating that exceeds the
drive rating should be chosen.

• IEC – BS88 (British Standard) Parts 1 & 2

• UL – UL Class CC, T, RK1 or J must be used.

Circuit Breakers

The “non-fuse” listings in the following tables include both circuit
breakers (inverse time or instantaneous trip) and 140M Self-Protect-
ing Motor Starters. If one of these is chosen as the desired protec-
tion method
