Description
1. Product Description
The GE Multilin SR469-P5-HI-A20-E is a motor management and protection relay designed to monitor, protect, and control industrial motors. Part of the 469 series, it integrates electrical protection, motor thermal monitoring, status supervision, and programmable control functions in a panel-mounted unit. It is suitable for industrial facilities, power distribution systems, and motor-driven equipment requiring comprehensive protection.
The model configuration includes 5 A phase current transformer (CT) inputs, high-range control power, four 4–20 mA analog outputs, and an enhanced front panel with an LCD display. Communication and configuration are supported through the relay’s serial interfaces and compatible setup software. Protection settings must be configured to match the motor nameplate, CT ratios, starting characteristics, and system protection coordination requirements.
