Type B23 312-10J for top-hat rail mounting 4TE, tariffs with integrated RS485 interface Modbus RTU. It features 2x inputs for controlling the tariffs or for counting external pulses and 2x outputs that can be configured as pulse output for active or reactive energy or as alarm output. Pulse length ranges from 10 to 990 ms for counting external pulses. Measuring accuracy for active energy is Class 1 and for reactive energy is Class 2 without MID. Connection cross-section measurement is 25 mm². Current measuring range is 0.25 to 65 A. Voltage range is 3x 220-240 AC with a tolerance of -20% to -15%. Frequency is 50-60 Hz. Temperature range is -40 to 70 degrees Celsius. The meter does not reset energy measurements and is calibrated according to MID and approved according to IEC B23 312-10J.
