1 / 1 page Function: 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) • ANSI/IEEE C37.90-1978 • UL file No. E58048 • CSA file No. LR61158 Several types of Reverse Power Relays are available including relays sensitive to reverse reactive power (KVAR). WILMAR is the leading brand of reverse power relays. Our rugged sealed construction provides con- tinuous and reliable operation unaffected by shock, vibration or other severe environments. Reverse Power Relays are used for the protection of generator sets operating in parallel. Reverse Power Relays PRODUCT SPECIFICATIONS 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. PART NUMBER SELECTION 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.
