PowerFlex 750-Series Products with TotalFORCE Control 5
Leakage Current
PowerFlex 750-Series products produce leakage current in the protective earthing conductor that exceeds 3.5
mA AC and/or 10 mA DC. The minimum size of the protective earthing (grounding) conductor that is used in the
application must comply with local safety regulations for high-protective earthing conductor current
equipment.
Motor Overload Protection
Short Circuit Current Rating
Branch Circuit Short Circuit Protection
• Branch circuit protection must be provided in accordance with the National Electric Code (NEC) and any
additional local codes, or the equivalent.
• Branch circuit protection for customer supplied 240/120V AC must have an AIC rating that is equal to or
greater than the product short circuit current rating.
Fusing
The recommended fuse types are listed here. If available current ratings do not match the ratings that are listed
in the tables provided, choose the next higher fuse rating.
• IEC – Use BS88 (British Standard) Parts 1 and 2, EN60269-1, Parts 1 and 2
(1)
, type gG or equivalent.
• UL – Use UL Class T, RK1, J, or L.
(1) Typical designations include, but may not be limited to the following; Parts 1 and 2: AC, AD, BC, BD, CD, DD,
ED, EFS, EF, FF, FG, GF, GG, GH.
Circuit Breakers
The ‘non-fuse’ listings in the following tables include inverse time circuit breakers and instantaneous trip circuit
breakers (motor circuit protectors). Both types of circuit breakers are acceptable for IEC installations.

ATTENTION: PowerFlex 750-Series drives with TotalFORCE control produce DC current in the
protective earthing conductor which can reduce the ability of RCDs (residual current-operated
protective devices) or RCMs (residual current-operated monitoring devices) of type A or AC to
provide protection for other equipment in the installation. Where an RCD or RCM is used for
protection in case of direct or indirect contact, only an RCD or RCM of Type B is allowed on the
supply side of this product.
Electronic motor overload protection Class 10 motor overload protection according to NEC article 430 and
motor over-temperature protection according to NEC article
430.126 (A)(2). UL61800-5-1 File E59272.
Maximum short circuit current rating Suitable for use on a circuit capable of delivering not more than 100
kA rms symmetrical amperes, up to 600V maximum and 65 kA rms
symmetrical amperes at 690V maximum.
Actual short circuit current rating May be further limited by AIC rating of customer supplied branch
circuit fuse/circuit breaker
