Description
GE 489-P5-HI-A20-EV
Technical Specifications:
- Brand: General Electric (GE)
- Model: 489-P5-HI-A20-E
- Product Type: Motor Management Relay
- Communication: RS-485 (Modbus RTU)
Functional Features:
- Comprehensive Protection: Protects against overload, phase loss, ground fault, and unbalance.
- Advanced Monitoring: Tracks motor temperature, current, voltage, and power factor.
- Thermal Modeling: Accurately models motor thermal capacity to prevent burnout.
Application Scenarios:
Industrial motor control centers, pump stations, compressor stations, and conveyor systems.
Performance Parameters:
High-accuracy metering, fast fault detection, and programmable protection curves.
Material Composition:
Ruggedized industrial enclosure, precision current transformers, and microprocessor-based logic.
Structural Characteristics:
Standard panel-mount enclosure with a digital display, navigation keypad, and rear terminal connections.
Working Principle:
Samples motor electrical parameters via CTs and VTs, evaluates them against programmed protection elements, and trips the motor contactor if limits are exceeded.
Installation Requirements:
Route CT and VT wiring away from high-voltage cables. Ensure proper grounding of the relay chassis.
Usage Precautions:
Configure CT ratios and motor nameplate data accurately. Perform periodic secondary injection testing to verify protection elements.
