Description

The Multi-Circuit Meter (MCM) is a kilowatt-hour (kWh) energy and power meter that communicates Modbus® RTU on an EIA RS-485 or Modbus TCP over Ethernet. It measures 1, 2, or 3 phases with voltages from 120 to 600 volts Vac and currents from 5 to 6,000 amps in delta (line-to-line) and wye (line-to-neutral) configurations. The MCM can be ordered in blocks of 12 CTs from 12 to 84 CT inputs (12, 24, 36, 48, 60, 72, or 84).

The MCM includes a NEMA rated enclosure, a DC power supply, circuit protection (fuses or circuit breaker), and terminal blocks, all prewired as a UL 508A Listed industrial control panel, ready for mounting. For more details see the specifications and downloads page.
