PowerFlex 700S and 700H Frames 10...14 IP00, NEMA/UL Open Power Structures
Electronic Motor Overload Protection
PowerFlex 700H and PowerFlex 700S drives provide Class 10 motor overload
protection according to NEC article 430 and motor over-temperature protection
according to NEC article 430.126 (A)(2). UL 508C File E59272.
Short Circuit Current Rating
Maximum short circuit current rating: 200,000 Amps symmetrical.
Branch Circuit Short Circuit Protection
Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the
NEC and any additional local codes, or the equivalent.
Fusing and Circuit Breakers
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 recommend fuse types are listed below. If available current ratings do not
match those listed in the tables provided, chose the next higher fuse rating.
• IEC – BS88 (British Standard) Parts 1 & 2, EN60269-1, Parts 1 & 2 (1)
,
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.
(1) Typical designations include, but may not be limited to the following; Parts 1 & 2: AC, AD, BC, BD, CD, DD, ED, EFS, EF, FF, FG, GF, GG,
GH.
