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.
Line Contactor Options
The Line Contactor option (option B10) offers a three-contactor isolation/bypass strategy when
Barriered Bypass is not required but when drive isolation while operating on bypass is desired.
