Non-fuse Circuit Breaker
Comply with the UL standard: Per UL 508, paragraph 45.8.4, part a.
The rated current of the non-fuse circuit breaker should be 1.6–2.6 times the drive’s rated input current.
The recommended current values are shown in the table below. Compare the time characteristics of the
non-fuse circuit breaker with those of the drive’s overheated protection to ensure that there is no tripping.
