PowerFlex 700 Adjustable Frequency AC Drive – Frames 0…6
Drive, Fuse & Circuit Breaker Ratings
The PowerFlex 700 can be installed with input fuses or an input circuit breaker.
National and local industrial safety regulations and/or electrical codes can
determine additional requirements for these installations.
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.
• IEC – BS88 (British Standard) Parts 1 & 2, EN60269-1, Parts 1 & 2
(1)
,
type gG or equivalent must be used.
• UL - UL Class CC, T, RK1 or J must be used.
Circuit Breakers
The “non-fuse” listings in the following tables include inverse time circuit
breakers, instantaneous trip circuit breakers (motor circuit protectors) and 140M
self-protected combination motor controllers. If one of these is chosen as the
desired protection method, the following requirements apply:
• IEC – Both types of circuit breakers and 140M self-protected
combination motor controllers are acceptable for IEC installations.
• UL - Only inverse time circuit breakers and the specified 140M self-
protected combination motor controllers are acceptable for UL
installations.
ATTENTION: The PowerFlex 700 does not provide branch short circuit
protection. Specifications for the recommended fuse or circuit breaker to
provide protection against short circuits are provided on pages
34 through 41 .
