Branch Circuit Short-circuit
Protection
This section covers branch circuit short-circuit protection that is provided by
configured input bays with input protection devices. If there is no configured
input bay or there is a control-only configured input bay (has no input
protection devices), then see the fuses and circuit breaker recommendations
for the standard drive. Those recommendations are provided in the PowerFlex
750-Series Products with TotalFORCE Control Installation Instructions,
publication 750-IN100
.
Branch circuit short-circuit protection must meet the following requirements:
• 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.
The following methods of input protection are used in the configured input
bays:
• Input Power Fuses on page 102
• Input Power Circuit Breakers on page 105
