108C
Motor Rotation IndicatorRead moreRotating an electric motor shaft in the wrong direction can cause severe mechanical damage to expensive machinery. The Model 108C Motor Rotation Indicator can quickly show shaft rotation direction, thus becoming a valuable addition to your shop equipment. Designed of the installation of conveyer lines, pump systems and interconnected drives, the Model 108C requires only a few seconds to determine the proper connections to be made. The three leads are color coded: Red=phase A, Black=phase B, and White=phase C. This small device will allow you to connect all motors to run the proper direction. -

Phase Sequence DetectorRead moreThis compact handheld Phase Sequence Detector can help you quickly and easily verify the wiring on your 3-phase applications. Connect the Detector to any 3-phase circuit with nominal operating voltage from 188 to 660 volts (Wye or Delta with operating frequencies of 50, 60, or 400 Hz) and LEDÕs will indicate phase sequence (ABC or CBA), phases present or missing and 400Hz frequency. A Low Battery lamp is also provided to indicate when the 9V battery needs to be replaced. This unit is engineered and built in the U.S.A. and has a 5-year warranty. -
208A-208/240V
Line Voltage & Phase Sequence DetectorRead moreThe Model 208A & 208D Line Voltage & Phase Sequence Detectors allows quick and easy determination of phase sequence (either ABC or CBA). Available in 50/60 Hz and 400 Hz versions, this unit can also show that all phases are present, or if one or more phases are lost, it indicates which of the phases are missing. To use, connect the Detector to any 3-phase circuit, Wye or Delta. In proper phase sequence, and with all phases present, the ABC lamp, and the three line voltage lamps will illuminate. An open phase condition will illuminate both rotation lamps and only two line voltage lamps. See the Condition Chart. -
