Low-Voltage Phase Sequence Indicator
■

Simply connect the lead wire clips to a main circuit so that the phase sequences and open phases can be easily checked.

■ This lightweight (130g) and compact (28x60X100mm) checker is pocketable.
■

Since the connections between the lead wires and main unit are safely constructed so that the live side is a plug-socket type, live parts are not exposed even if the socket is disconnected by chance.

■

Lamp indication of measurement results allows reliable judgment.

■

The maul unit requiring no batteries for measurement and indication. is economical. At check time, however, circuit voltage needs to be applied.
