Benefits

• Provides accurate frequency protection for a distribution system

or generator operating at 50 or 60 Hz.

• Accurate, repeatable, and reliable operation.

• Incrementally-staged load shedding possible with up to four

independent frequency set points.

• Flexible protection options with selectable overfrequency or

underfrequency sensing for each set point.

• Clear settings indication from individually adjustable time delays

and LED indicators for each frequency set point.

• Minimized PT (potential transformer) costs as a result of low

sensing burden.

• Reduced battery load with low burden power supply.

• LED targets provide clear annunciation of status.

• Easily perform in-case system and device tests using test plugs.
