Time Mark 108D

PH SEQ DET,90-600VAC,(98053202)

This Line Voltage & Phase Sequence Detector will allow you to quickly and easily determine the proper phase sequence (either ABC or CBA) to install, or make wiring changes to motors, watt-meters, transformers, electrical installations, power factor meters or generators. It will show each individual phase and if any phases are missing. To use, connect the Detector to any 3-phase circuit from 90 to 600 volts, 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. This unit is for 400 Hz (Model 108A is for 50/60 Hz).
