The SR469-P5-HI-A20 GE American relay is a motor management relay primarily used in industrial and power systems to protect motors and related equipment from potential failures and overloads. Here are the details about the relay:

Manufacturers and Brands:

Manufacturer: General Electric

Brand: GE

Model and logo:

Model: SR469-P5-HI-A20

Main functions:

Motor management: Used to monitor motor operating status, current, temperature, etc., and protect the motor from potential failures and overloads.

Provide protection functions: such as over current protection, over temperature protection, short circuit protection, ground gate protection, etc., to ensure the safe operation of the motor.

Technical parameters:

Four 4-20 mA analog outputs.

Bearing the CE mark.

The control power supply is rated 90-300 VDC, 70-265 VAC @ 48-62 Hz.

Provides motor thermal model functions such as RTD bias, motor cooling time constant, start suppression and emergency restart, unbalanced bias and overload curves.

Physical characteristics:

The side design allows airflow to be maintained within the proper operating temperature range.

Contains a front panel with LCD display, multiple LED indicator areas, a dedicated keyboard for input, and a communication port.

Scope of application:

It is mainly used in power systems, including power distribution, industrial motors, power plants and substations.

Additional information:

The device is a standard device with a 5A phase CT secondary side.

One of the two grounded CT inputs is designed for GE power management, while the other is for grounded CT.

The VT input will accommodate the VT in a triangle or star configuration.
