60V to 600V three phase testing: The instrument can check a wide range of 60V600V three phase systems, guaranteeing reliability and performance. Phase sequence and open phase detection: It checks the phase sequences and uses LEDs to show if a phase is open or not, enabling quick identification of wiring issues. 3 Phase Sequences Presences Rotation Tester: This model ensures accurate detection of phase sequences and open phases, providing critical insight for electrical and systems stability. Easy testing of control panel terminals: It easily tests the terminals of the control panel, guaranteeing reliability. Use scenarios Commissioning three phase equipment such as motors, conveyors, or drives in manufacturing or facility management to verify voltage range, phase sequence, and the presence of all phases before startup. Routine maintenance of switchboards or control cabinets to quickly identify incorrect phase rotation or open phase conditions and prevent equipment damage. Field service at industrial sites to verify phase integrity and correct wiring prior to energizing equipment.
