Class 8839 58M Enclosed AC Drives

Power Circuit Descriptions

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.
