Time Mark 125C

400 HZ PH SEQ DET,208-480VAC,(98000201)

Phase Sequence Detector

Quickly and easily determine proper phase sequence (either ABC or CBA) with this Phase Sequence Detector. This can be vitally important information when installing, or making wiring changes to motors, wattmeters, transformers, electrical installations, power factor meters or generators. To use, connect the Detector to any 3-phase circuit from 208 to 480 volts, Wye or Delta. Proper phase sequence and all phases present will illuminate the ABC lamp and the three voltage lamps. An open phase condition will illuminate both lamps. If two or more phases are open, neither lamp will illuminate. This unit is for 400 Hz (Model 108B is for 50/60 Hz).
