3. Comply with the UL standard: Per UL 508, paragraph 45.8.4, part a.
2. The rated current of the non-fuse circuit breaker should be 1.6 to 2.6 times the drive’s rated input current. See
the table below for the recommended current values. 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.
