1. When semiconductor fuses are used for UL listed drive protection, the drives and fusing must be in the same enclosure. Where multiple semiconductor fuse
ratings are listed for a single drive, Yaskawa recommends the larger fuse for cyclical load applications that frequently approach 150% overload. Smaller
semiconductor fuses (than what is listed) of the same manufacturer and series are permitted; however, this may cause fuses to clear prematurely.
2. When using class CC, J, or T fuses as UL listed drive protection, models 4371 and larger have the same enclosure requirements as MCCBs.
3. When using MCCBs, RK1 fuses, or RK5 fuses as UL listed drive protection, the drives must be mounted in ventilated enclosures according to the minimum
enclosure volume specified. When using MCCBs, Yaskawa recommends current limiting type.
