Three-phase meter for measuring a three-wire or four-wire three-phase network via a direct connection up to a maximum of 65 A. The following values are output via a seven-segment display with up to 7 digits: active energy (class 1), power, currents, voltages (LL, LN) and frequency, both per phase and total. Communication can take place via the integrated RS485 interface (Modbus RTU) or via the infrared interface for connecting a KNX module. The energy meter has a pulse output. The meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules.
