■ Introduction
ᆞ Digital three-phase Ammeter and various Motor protection function.
The amount of the three-phase current is each displayed by
pressing the key. In normal, the maximal current is always displayed.
ᆞ By using the Bar-LED arrays. The loading ratio is always displayed
from 60% to 110% in normal.
ᆞ Extensive current range : 0.5 ~ 60A
ᆞ The trouble cause is displayed in the indicator,is easy to recover it.
!
WARNING
ᆞ Trun off the upstream breaker before installing or service to
prevent electric shocks and burn due to short circuit.
ᆞ Do not touch any live naked terminals.
It make an electric shock.
ᆞ Install the noise filter in the external,if the harmonic is
more than 30%
It may cause a malfunction.
!
CAUTION
