1 / 1 page Function: 42 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 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. Operation: The normally open contacts close, and the normally closed contacts open, at nominal frequency. The contacts are de-energize at underfrequency, overfrequency or no input voltage. Frequency Sensitive Relays PRODUCT SPECIFICATIONS Sample Part No. 25-050X Type: 25 - Over/Underfrequency Frequency Range Under Over 050 = 40-50 Hz 50-60 Hz 060 = 50- 60 Hz 60-70Hz 400 = 350- 400 Hz 400-450Hz Mounting Options X = Flange blank = Stud Consult factory for additional models. PART NUMBER SELECTION Notes: 1. The contacts are shown in the de-energized position. 2. Remove screws for access to the underfrequency and overfrequency trip adjustments. 3. Clockwise rotation of the adjustment potentiometer will raise the frequency trip points. PART NUMBER SELECTION Part Number Input Voltage ( ±10%) ......................
