ABB REM545 Motor Terminal Legacy Spare and Replacement Enquiries

ABB REM545 is a legacy machine protection terminal used for motor, generator and generator-transformer protection.

Description

ARP IMPEX supplies and exports ABB REM545 motor protection terminals for industrial motor, generator and rotating-machine protection requirements.

REM545 is part of ABB’s REM54x machine protection terminal range. It combines protection, control, measurement, condition monitoring and communication functions in one unit. ABB developed the terminal for large or important medium-voltage synchronous and asynchronous motors as well as generators and generator-transformer units.

Depending on the installed configuration, REM545 can cover motor thermal overload, short circuit, earth fault, phase unbalance, motor starting and stall conditions. Generator-related functions such as differential protection, abnormal frequency, under-excitation, reverse power and other protection functions were also available within the REM54x platform.

One useful difference between REM543 and REM545 is the available input/output capacity. ABB specifies 25 binary inputs and 18 output relays for REM545, making it suitable for panels where more control, signalling and interlocking points are required. An optional RTD arrangement was also available for temperature monitoring.

ABB supplied REM545 with different protection and hardware configurations, so the complete order code should be checked when sourcing a matching unit.

Features

• Motor thermal overload protection
• Short-circuit protection
• Earth-fault protection
• Motor phase-unbalance protection
• Motor start-up supervision
• Stall protection
• Cumulative start supervision
• Generator protection functions depending on configuration
• Temperature monitoring with optional RTD inputs
• Local and remote equipment control
• Programmable logic for interlocking and sequencing
• Current, voltage and power measurement
• Circuit-breaker condition monitoring
• Trip-circuit supervision
• Communication with higher-level automation systems

The actual functions available in a particular REM545 depend on its original configuration. For an existing terminal, the ABB order code and nameplate provide a better starting point than the model name alone.

Applications

ABB REM545 is suitable for:

• Medium-voltage motor protection
• Large asynchronous motors
• Synchronous motors
• Pump motors
• Fan motors
• Mill motors
• Crusher motors
• Critical industrial drives
• Generator protection
• Generator-transformer protection
• Diesel power plants
• Hydroelectric power plants
• Steam power plants
• Industrial power systems
• Marine applications
• Offshore installations

ABB specifically documents REM543 and REM545 for large or important MV motors used in pumps, fans, mills and crushers, as well as generator and generator-transformer units in small and medium-sized power plants.

ABB REM54x Machine Protection Terminal Family

The ABB REM54x family includes REM543 and REM545. Both are machine protection terminals covering protection, measurement, control, condition monitoring and communication. Their main hardware difference is the number of digital inputs and outputs available.

ABB REM543

REM543 is the lower-I/O version of the REM54x family. It is used where the required number of control, indication and interlocking points is lower.

ABB REM545

REM545 provides the larger I/O arrangement with:

• 25 binary inputs
• 18 output relays
• Optional RTD inputs

This makes REM545 useful for motor or generator panels where more external signals, control points and interlocking functions need to be handled by the terminal.

REM543 and REM545 belong to the same product family, but the installed hardware and configuration should be checked when sourcing a replacement.
