GENERAL ELECTRIC T60N00HKHF8NH6TMXXP6UUXXWXX | Transformer Management Relay

Product Overview

The GENERAL ELECTRIC T60N00HKHF8NH6TMXXP6UUXXWXX is a GE Multilin T60 Transformer Management Relay from the UR Series. It is designed for transformer protection, monitoring, control, and electrical measurement applications in industrial and power-system installations.

This configuration is identified with a T60 front panel and a modular UR architecture. Available identification records show a combination of power, CPU/communications, CT/VT, and digital I/O modules, making the unit suitable for applications where transformer protection functions and system monitoring are integrated into one relay platform.

The complete model number is important when sourcing a replacement because the T60 platform is available in many different hardware configurations.

The module-level information above comes from identification records for this specific unit/configuration. Because UR hardware is modular, verify the actual nameplate, rear terminals, module labels, and firmware before using these values for an engineering replacement.

Hardware Configuration

The available identification information provides a useful picture of the installed hardware:

Power Supply:
The RH section is identified with 125–250 VDC and 100–240 VAC input capability, with a listed power rating of 35 W / 35 VA.

CPU / Communications:
The configuration identifies a UR 9N CPU section and lists RS485 and 10/100 Base-T Ethernet communications.

CT / VT Section:
The UR 8N section is identified for phase CTs and ground CT measurement, with 1 A / 5 A CT inputs and four VTs listed in the configuration.

Digital I/O:
The listed configuration includes UR 6T and/or 6U digital I/O modules. One configuration identifies 4 Form-A outputs with 8 digital inputs, while another 6U section is identified with 6 Form-A outputs and 4 digital inputs. Check the installed module labels before relying on the exact I/O count.

Application

The T60 is intended for transformer protection and management applications where multiple protection, measurement, control, and communication functions are required.

Typical applications include:

Power transformer protection
Substation transformer monitoring
Industrial power distribution
Transformer control and automation
Electrical measurement systems
Generator and transformer protection schemes
Utility and industrial substations
Legacy GE Multilin protection systems

For an existing installation, the relay’s complete configuration should be matched rather than replacing it solely by the “T60” family name.

Installation & Configuration

Before installing a replacement relay, record the existing unit’s:

Complete model number
Serial number
Firmware version
Power-supply configuration
CT and VT wiring
Digital input/output assignment
Communication settings
Protection settings
Existing wiring diagram
Module positions and identification labels

The configuration associated with this model is documented with wiring diagram 828712.

CT and VT wiring should be checked carefully before energizing the relay. Incorrect CT connections or protection settings can cause incorrect measurements or unwanted protection operation.

For a field replacement, back up the existing protection settings and communication configuration whenever possible.

Maintenance Recommendations

For an installed T60 relay, periodic inspection should include:

Power-supply terminals
CT/VT input terminals
Digital I/O wiring
Ethernet and serial communication ports
Front-panel display and keypad
Cooling and cabinet conditions
Alarm and diagnostic records
Firmware identification
Protection-setting backup

Keep the relay cabinet clean and dry. Before replacing individual modules, compare the module part number and hardware revision with the original unit.

Replacement Notes

The full catalog string T60N00HKHF8NH6TMXXP6UUXXWXX should be used when searching for a like-for-like replacement.

Do not assume that another GE Multilin T60 with a similar front panel is electrically equivalent. The UR platform uses modular hardware, and power supply, CT/VT, communications, and digital I/O configurations can differ between units.

The available records also show different firmware identifiers, including A09MA590.000 and A09MA601.000, so firmware should be checked on the actual relay before commissioning.
