Anti-tamper Three Phase Four Channel Smart Electricity Meter
Product Description
The CA-2 is a cost-effective solution for smart metering, data
reading and load balance operations. 3 Phase Kilowatt Hour Meter goes with four wire direct connection type, 100 Amp per phase in a
compact BS housing. CT(Current Transformer) connection type with
1.5(6) Amp per phase is also available on request. 3 Phase Kilowatt Hour Meter is ideal for large residential homes, small commercial and
industrial applications.
