Specifications

Description

The GE Multilin 469-P5-HI-A20-E-H is a high-performance motor management relay meticulously crafted for the industrial automation sector, holding a significant position in GE Multilin's 469 series. Its core mission is to provide comprehensive and reliable protection as well as precise management for medium to large motors, being widely applied in various industrial scenarios with extremely high requirements for motor operation stability.

Applications

Large-scale smelting plants: Provide comprehensive protection for blast furnace blowers and heavy-duty crusher motors, offering accurate heat capacity analysis in high-temperature, dusty environments.

Oil refineries: Manage the power of critical compressors and long-distance oil pumps, transmitting operating power and temperature rise to the central control room in real time via analog output.

Mining plants: Deployed in open-pit mine hoists and conveyor belt systems, relying on enhanced protective design to withstand harsh weather and mechanical vibrations.

Combined cycle power plants: Monitor the electrical status of circulating water pumps and auxiliary power systems, utilizing high-speed waveform recording for rapid fault tracing.

Pulp processing plants: Coordinate the startup logic of large grinding mills and mixing equipment, optimizing the plant's overall energy efficiency through real-time power metering.

Functional Features

Overload Protection:

It monitors motor current in real time. When overload is detected, it quickly triggers protection by cutting power or reducing output, preventing winding overheating and extending motor life.

Short Circuit Protection:

It instantly detects short-circuit faults and rapidly trips the relay to isolate the circuit, preventing severe damage to the motor and related equipment.

Ground Fault Protection:

Using zero-sequence and sensitive ground current inputs, it detects leakage currents and quickly alarms or trips, preventing electric shock risks and ensuring safe system operation.

Physical Design and Interface

Case Design: Uses a fixed case and draw-out unit for mechanical protection.

Ventilation & Cleaning: No special ventilation required; can be cleaned with a damp cloth.

Mounting: Can be used in a single or double cutout panel.

Front Panel:

Display: Features a 40-character display.

LED Indicators: Three groups of LED indicators for 469 status, Motor Status, and output relay status.

Controls: Includes a programming port, a numerical keypad, and eight additional buttons.
