Product Overview
The MMII‑PD‑1‑2‑120 from GE Multilin (part of the MMII Motor Manager II family) is a microprocessor-based motor management, monitoring, and protection relay designed for industrial motor control applications powered from 120 VAC auxiliary supply. It integrates comprehensive protection functions (e.g., thermal overload, phase imbalance, ground fault, stall detection) with process control, real-time diagnostics, metering, and communication support, making it suitable for motor control centers (MCCs), pumps, compressors, fans, and other critical rotating equipment. The panel-mounted unit includes a local display and keypad for configuration and status viewing, while optional Modbus RTU remote communication enables SCADA/DCS integration.
