Ratings
The tables on the following pages provide recommended AC line input fuse and
circuit breaker information. See Fusing and Circuit Breakers below for UL and
IEC requirements. Sizes listed are the recommended sizes based on 40 °C (104
°F) and the U.S. NEC. Other country, state, or local codes can require different
ratings. Tables with DC link fuse recommendations for DC input drives are also
provided.
Fusing
The recommended fuse types are listed below. If available current ratings do not
match those listed in the tables provided, choose the next higher fuse rating.

type gG or equivalent should be used.
•
UL - UL requirements specify that UL Class CC, T, or J fuses must be
used for all drives in this section.
Circuit Breakers
The “non-fuse” listings in the following tables include inverse time circuit
breakers and instantaneous trip circuit breakers (motor circuit protectors). If one
of these is chosen as the desired protection method, the following requirements
apply:
•
IEC – Both types of circuit breakers are acceptable for IEC installations.
•
UL – Only inverse time circuit breakers are acceptable for UL
installations.
