Schneider Electric CM-150 CM150X1 Circuit Monitor

The Schneider Electric Square D PowerLogic CM-150X1 Circuit Monitor (CM-150) is a compact, single-branch PowerLogic instrument that replaces multiple meters in a control system by delivering real‑time metering data for 120 V AC feeders. It accepts 0–180 V AC input (nominal 120 V) with 1 MΩ input impedance and measures 0–7 A (nominal 5 A) with overload ratings of 15 A continuous, 50 A for 10 seconds per hour, and 500 A for 1 second per hour. Its internal power supply operates from 102–132 V AC, 20 VA, and it tolerates 45–65 Hz operation with a ride-through time of 244 ms at 120 VAC. Measurements include voltage, current, frequency, power, energy, and power factor, and all data are accessible via RS-485 (RS-422-compatible) communications to a local display, PC, or master controller. Accuracy specs typically list voltage/current at ±1%, power at ±2%, frequency at ±0.5%, power factor at ±4%, and energy at ±2%. The CM-150X1 is designed for use within Square D PowerLogic System 1, supporting up to 32 circuit monitors on a single system for scalable feeder monitoring in commercial or industrial facilities, enabling energy accounting and informed control decisions.
