ABB REF545 Legacy Spare, Replacement and Modernisation Support

ABB REF545 is a legacy feeder protection and control terminal and is listed by ABB as not active since 2022. For replacement or modernisation, the existing order code, product revision and configuration should be checked first.

Description

ARP IMPEX supplies and exports ABB REF545 feeder terminals for medium-voltage feeder protection, control and existing REF54x installations.

REF545 is part of ABB’s REF54x feeder terminal family. It combines protection, breaker control, measurement, condition monitoring and communication functions in one unit. ABB designed the terminal for different medium-voltage switchgear arrangements, including single-busbar, double-busbar and duplex systems.

Compared with REF541 and REF543, REF545 provides the highest input/output capacity in the REF54x family. ABB specifies 34 binary inputs and 26 output relays, making the terminal suitable for applications where a larger number of control, indication and interlocking points are required.

The protection functions depend on the original REF545 configuration. Apart from feeder protection, ABB documentation also covers applications involving medium-sized three-phase asynchronous motors and shunt capacitor banks. REF545 also has programmable PLC functions that can be used for automation, interlocking and sequence logic within the substation.

For ABB REF545 price, availability, legacy spare or replacement enquiries, send the complete ABB order code, clear nameplate photograph, quantity and destination country. The complete order number is important because REF54x terminals were supplied with different hardware, software and functionality levels.

Technical Specifications

• Brand: ABB
• Family: REF54x / RE500
• Model: REF545
• Product type: Feeder protection and control terminal
• Product status: Not active since 2022
• Application: Medium-voltage protection and control
• Binary inputs: 34
• Output relays: 26
• Protection functions: Depend on selected configuration
• Control: Local and remote switching-device control
• Measurement: Current, voltage and other electrical measurements depending on configuration
• Condition monitoring: Available
• Programmable logic: PLC functions for automation and interlocking
• Communication: SPA, LON and IEC 60870-5-103
• IEC 61850: Available through SPA-ZC 400 communication adapter
• Additional communication: Profibus DPV1, DNP 3.0 and Modbus through applicable interfaces

The actual protection and control functions should be confirmed from the installed REF545 rather than assumed from the model number alone.

Features

• Feeder overcurrent and earth-fault protection
• Circuit-breaker control
• Local and remote switching
• Current and voltage measurement
• Condition monitoring
• Fault and disturbance information
• Programmable interlocking
• Automation and sequence logic
• Large number of binary inputs and output relays
• Communication with higher-level substation systems
• Local operating interface
• Internal self-supervision

One of the main differences between ABB REF545 and REF541/REF543 is its larger I/O capacity. This can be important when checking a replacement for an existing panel with extensive control, indication and interlocking wiring.

Applications

ABB REF545 can be used for:

• Medium-voltage feeder protection
• Incoming feeder panels
• Outgoing feeder panels
• Cable feeder protection
• Utility distribution substations
• Industrial power distribution systems
• Single-busbar switchgear
• Double-busbar switchgear
• Duplex switchgear
• Isolated-neutral networks
• Resonant-earthed networks
• Partially earthed networks
• Medium-sized asynchronous motor applications
• Shunt capacitor-bank protection and control
• Feeder automation and interlocking
• Substation automation systems

ABB specifically documents REF545 for medium-voltage network protection and control as well as motor and shunt capacitor-bank applications, depending on the selected functionality.

ABB REF54x Feeder Terminal Family

REF545 belongs to the ABB REF54x family, which mainly includes:

ABB REF541

The lower I/O version of the REF54x family, suitable where fewer control, indication and interlocking points are required.

ABB REF543

The intermediate model with more I/O capacity than REF541.

ABB REF545

The highest I/O version of the three, with 34 binary inputs and 26 output relays.

ABB REF545 Functionality Levels

ABB supplied REF54x terminals with different functionality levels:

• C – Control: Control, condition monitoring and measurement functions
• B – Basic: Control, monitoring and measurement with basic protection
• M – Multi: Wider protection, control, monitoring and measurement functions

Additional functions were available depending on the selected application.

ABB REF545 Replacement and Modernisation

ABB REF545 is a legacy product, so an existing terminal should first be identified from its order code, revision and configuration.

ABB currently includes REF541, REF543 and REF545 within its system retrofit scope.

Depending on the project, ABB lists migration possibilities toward Relion platforms including REX610, 615-series, 620-series and REX640. ABB also states that these migrations are site-specific and require checking the existing switchgear drawings, mounting arrangement, I/O, application and parameter configuration.

For a REF545 replacement or modernisation enquiry, please provide:

• Complete ABB REF545 order code
• Clear nameplate photograph
• Hardware/software revision, if available
• Quantity
• Destination country
• Required delivery date

Configuration files or existing panel drawings can be checked later if required for a modernisation project.
