STATIC 3-PHASE WHOLE CURRENT

ENERGY METER
(WITH DOOR OPEN “SOLUTIONS FOR THE FUTURE”

FEATURE)
VTX-34

VTX-34 is Electronic Three Phase Four Wire Whole

Current Energy Meter developed for residential and
commercial users. This meter is developed for measure-
ment of Active and Re-active energy and also includes
maximum demand and Multi-tariff features. This model
upholds advanced Anti- Tempering features and suitable
for high power theft areas. current.

These meters comply with the

IEC 62053-21 & 62053-23 for
Accuracy Class 1.0 for active en-
ergy and Class 2.0 for re-active
energy measurement.
