PART NUMBER SELECTION Sample Part No. 710X Type: ± 20% 710 = 120 V, 220 V, 266 V line to neutral 720 = 120 V, L-L, 3 Phase 721 = 230 V, L-L, 3 Phase 722 = 380 V, L-L, 3 Phase 723 = 460 V, L-L, 3 Phase 724 = 575 V, L-L, 3 Phase 725 = 416 V, L-L, 3 Phase Mounting: X = Flange Blank - Stud Options: 7 = Reverse Inductive P = Surge Suppression Consult factory for additional models. 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) 0.400
