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 displayed on a seven-segment display with up to 7 digits: active energy (Class 1), power, current, voltage (L-L, L-N), and frequency, both per phase and total. Communication can occur via the integrated infrared interface for connecting a KNX module. The energy meter has an output that can be used either as a pulse output for active energy or as an alarm output. Up to 25 alarm values (thresholds with time delay) can be set here. The meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules. The ABB Stotz S&J three-phase meter B23 111-100 is supplied.
