The digital three-phase meter 3Ph72-2R-2T-100A for the top hat rail (4 TE), with 7-segment LCD display for direct connection, measures the active power of the flowing currents (nominal current 10 A) (limit current 100 A). In addition to a 2-way counter, it also contains the extended function of a 2-tariff meter (HT/NT). The daily counting function for (import and export) is freely resettable. Current consumption display in watts for import and export. RS485 Modbus RTU interface. S0 interface with 1000 pulses/kWh.
