| Frequency Sensitive Relays WILMARTM Protective Relays - 20-000 Series Function: 81 O The output contacts of frequency relays are energized 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 available. These are energized at rated frequency and deenergized during overfrequency or underfrequency conditions. Frequency Differential relays are energized between the preset frequencies. The pick-up and drop-out frequency settings are independently adjustable. 4 1/2 #6 - 32 STUDS 6 PLACES Operation: The normally open contacts close, and the normally closed contacts open, at all frequencies above the set point. The contacts in the connection diagram, are shown in the de-energized position (below the trip set point). 3 13/16 Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm. Part Number Input Voltage (10%) ...................... 120 VAC, Single Phase Frequencies Range (adjustable) ...... See Part Number Selection Differential ........................................
