Transformer kilowatt-hour meter 1A A44 552-100 – ABB – 2CMA170545R1000 – 7392696705455: Instrument transformer meter RS485 A44 552-100 Electronic meter type, rated current (In) 1A, maximum current (Imax) 6A, rated voltage (Un) NL 57.7 ... 288V, rated voltage (Un) LL 100 ... 500V, frequency 50 ... 60Hz, accuracy class C, Polart four-wire, measuring transducer version, energy type active and reactive power, suitable for import/supply, tariff design multi-tariff, tariff control internal/external, measurement type load profile, backstop, calibrated, approval Measuring Instruments Directive, pulse output electrical, pulse type S0, pulse rate 5000 ... 5000Imp/kWh (kvarh), display type digital, mounting type REG, width in division units 7, design of the interface RS-485, number of digits 7, protection class (IP) IP20, protection class (NEMA) other, three-phase meter for measuring a Three-wire or four-wire three-phase network via a CTVT converter connection (configurable converter ratio for current and voltage) up to a maximum of 6 A. The following values are output via a backlit display with up to 7 digits level: active energy (class 0.5) and reactive energy (class 2) for import and export, power, currents, voltages (LL, LN), frequency, cos phi, power factor and apparent power (per phase and total). Communication can take place via the integrated RS485 or infrared interface. The energy meter has 4 individually programmable inputs/outputs. The output can be used either as a pulse output or as an alarm output (up to 25 alarm values). The inputs are used to control the tariffs or to count external pulses. In addition, the meter records up to 4 tariffs. The energy meter measures currents and voltages up to the 16th harmonic and uses it to calculate the total harmonic distortion. Meter is calibrated according to MID and approved according to IEC. The installation width is 7 DIN modules.
