The output contacts of frequency relays are ener-

gized when the frequency exceeds the adjustable set

point. Overfrequency and underfrequency relays are

available in 50, 60, and 400Hz. Combination over/

underfrequency “band pass” relays are also avail-

able. These are energized at rated frequency and de-

energized during overfrequency or underfrequency

conditions. Frequency Differential relays are ener-

gized above the preset frequency. The pick-up and

drop-out frequency settings are independently ad-

justable.
