Branch Circuit Protection for 400 V Class (HD)

Use the fuses specified in this document to prepare the drive for use on a circuit that supplies not more than
100,000 RMS symmetrical amperes and 480 Vac when there is a short circuit in the power supply.
The built-in short circuit protection of the drive does not provide branch circuit protection. The user must provide
branch circuit protection as specified by the National Electric Code (NEC), the Canadian Electric Code, Part I
(CEC), and local codes.
