Sample Part No. 720TDX Type: 710TD = 120V, 220V, 266V line to neutral 720TD = 120V, L-L, 3 Phase 721TD = 230V, L-L, 3 Phase 722TD = 380V, L-L, 3 Phase 723TD = 460V, L-L, 3 Phase 724TD = 575V, L-L, 3 Phase 725TD = 416V, L-L, 3 Phase 730TD = 120 V, 230 V, 380 V, 460 V, L-L, 3 Phase or 120 V, Single Phase, L-N Mounting: X = Flange Blank - Stud Options: 7 = Reverse Inductive, 60 Hz Notes: 1. Remove screw for access to the pick-up and time delay adjustments. 2. Clockwise rotation of the pick-up adjustment will raise the reverse trip point. 3. Clockwise rotation of the time adjustment will increase the time delay. Consult factory for additional models. 4. Polarity of the voltage and the current connections must be observed for true power sensing. 5. Interchanging connections on terminals 5 and 6, will cause the output contacts to pick-up on forward power and dropout on no power or reverse power.
