Hager 3 Phase 3 Pole + N kWh Energy meter via CT EC320

Hager 3 Phase 3 Pole + N kWh Energy meter via CT EC320

This kilowatt hour meter measures the active electrical energy used in an electrical installation. It features a total counter, a resettable partial counter, and a calibrated pulsed output. Additionally, in the case of two tariff levels, the EC 321 can separately count the energy used in tariff 1 and tariff 2.
