ABB Measuring transformer meter

Three-phase meter for measuring a three-wire or four-wire three-phase network via a transformer connection CT (transformer ratio for current configurable) up to a maximum of 6 A. The following values are displayed on a seven-segment display with up to 7 digits: active energy (class 0.5) and reactive energy (class 2) for import and export, power, currents, voltages (L-L, L-N), frequency, cos phi, power factor, and apparent power, both per phase and total. Communication can occur via the integrated RS485 interface (Modbus RTU) or through the infrared interface for connecting a KNX module. The energy meter has 2 fixed-configured inputs and outputs. The output can be used either as a pulse output for active or reactive energy or as an alarm output. Up to 25 alarm values (thresholds with time delay) can be set here. The inputs are used for controlling tariffs or for counting external pulses. The resettable intermediate counter allows for measuring individual intervals. Additionally, the meter can record up to 4 tariffs. The meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules.
