Issue:
Can I-line and NF panelboards be used at 400 Hz frequency?
Product Line:
Panelboards
Environment:
I-line / NF Panelboards
Resolution:
Yes, I-line and NF panelboards are rated for use at 400hz. Rerating of breakers due to the higher frequency is necessary and can be calculated with attached data bulletin 0100DB0101. NOTE: Please note that rerating information for higher frequencies (and other special conditions) for the Powerpact family of circuit breakers is to be found in the catalog section of each specific circuit breaker, rather than aggregated into a single publication such as the one attached to this FAQ.
