Harmonic Filter Options
The Harmonic Filter option (option 710) provides integrated short circuit protection for separately mounted harmonic filters by coordinating the Class 8839 58M Enclosed drive's circuit breaker as a common disconnect for both filters and drive. Branch circuit protection is also provided with fuses according to the National Electrical Code. This option is wired so that it does not affect bypass operation when supplied.
