UNI-T UT261A Phase Rotation Tester and Motor Speed Indicator

Product detailed description

UNI-T UT261A Phase Rotation Tester and Motor Speed Indicator
We offer a 3-year warranty on this product. The UT261A phase sequence detector is used to check the order of connection of phase wires in three-phase motors where the direction of rotation must be observed. After connecting the three enclosed measuring cables to the L1, L2, L3 sockets on the UT261A device and the other end with the croc clamps to the motor supply wires, the direction of rotation of the motor axis clockwise or counterclockwise is displayed on the LCD display.
