GE Multilin 469-P5-LO-A20-E-H Motor Management Relay Unit

Feature & Principle

This pluggable motor protection relay adopts advanced thermal model algorithm. It collects current, voltage and RTD temperature signals, realizes overload, unbalance, earth fault, locked rotor and over-torque protection. It supports event log and waveform recording, communicates via RS232 / RS485 Modbus, can upload running data and alarm information to SCADA system. Draw-out structure facilitates quick replacement without disconnecting CT circuit.
