Model 710X = 120 V, 220 V or 266 V Line Frequency ................................. 50-500 Hz. Current Requirements ..................... 0 to 5 amp max direct or from CT with 5 amp secondary Trip Adjustment ............................... Screwdriver adjustable 4% to 20% (of the 5 amp rating) Time Delay ........................................ Inverse Delay - See Chart Output Contacts ............................... One set N.O., one set N.C. Contact Ratings ................................ 5 amp resistive at 120 AC or 28 Vdc Power Consumption ........................ Voltage circuit: 2 VA max. Current circuit: 4 VA max. Notes: 1. Remove screw for access to the pick-up adjustment. 2. Clockwise rotation of the adjustment will raise the reverse trip point. 3. This relay senses true power, which is a product of voltage, current and phase angle. Connections and polarity must be obversed in accordance with the provided diagrams. 28 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)
