1 / 1 page Function: 39 Tyco Electronics / www.tycoelectronics.com / Factory Direct Technical Support: 800-253-4560, ext. 2023 (U.S., Canada, Mexico) or 805-220-2020, ext. 2023 (International) • ANSI/IEEE C37.90-1978 • UL file No. E58048 • CSA file No. LR61158 Application: 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. Frequency Sensitive Relays PRODUCT SPECIFICATIONS Sample Part No. WUF-12-5060-T Type: WUF = Underfrequency WOF = Overfrequency Input Voltage (VAC) 12 = 120 23 - 230 38 = 380 46 = 460 Frequency Range 4050 = 40-50 HZ 5060 = 50-60 HZ 6070 = 60-70 HZ 3540 = 350-400 HZ 4045 = 400-450 HZ (overfrequency only) Time Delay Options blank = Per Time Curve T = Adjustable Consult factory for additional models. PART NUMBER SELECTION Notes: 1. Remove black screws for access to the frequency and the time adjustments. 2. Clockwise rotation of the frequency potentiometer will raise the frequency trip point. 3. Clockwise rotation of the time adjustment, option "T" will increase the time for overfrequency relays and dropout time for underfrequency relays..

Adjustment range in accordance with ordering information. -20oC to +65oC The frequency pitch-up to drop-out differential is .5% max ± .05% maximum frequency error for input voltage variation of ±10% See Time versus Frequency curves In compliance with C37.90B ANSI/IEEE One set N.O., one set N.C. 5 amp resistive at 120 VAC or 28VDC Time Delay Standard Time Delay A minimum, fixed inverse time delay is incorporated in all frequency relays to prevent nuisance tripping and is represented by the typical curves shown below. Adjustable Time Delay If additional time delay is required, a suffix "T" must be added to the part number. This allows the minimum fixed time delay to be field-adjustable up to 20 seconds 11 /64" DIA. 4 HOLES 2 1/2 3 1 /2 4 1 /4 Typical Curves (WUF Series) 30 35 40 45 50 55 60 01 23 45 6 Drop-Out Time Delay Typical Curves (WOF Series) 60 65 70 75 80 85 90 0 1 2 3456 Pick-Up Time Delay (sec) 81 O/U WILMAR™ Protective Relays – WOF & WUF Series Note: Dimensions in inches.
