Factory Recommended Branch Circuit Protection
Yaskawa recommends installing one of the following types of branch circuit protection on a secondary circuit of a 6-
Phase/12-Pulse transformer to maintain standards compliance.
Refer to local codes for proper Branch Circuit Protection on the primary circuit of a 6-Phase/12-Pulse transformer.
The maximum Time Delay fuse is 175% of drive input current rating listed in
class fuse.
A Class L fuse is also approved for this rating at 175% drive input current listed in
