ABB has introduced a new motor protection device, the REM545AG228AAAA, which is part of the REM 543/545 series of motor terminals. The device integrates a variety of protection, measurement and control functions to provide comprehensive protection and monitoring of industrial motors.

Key features of REM545AG228AAAA devices include:

Protection function: Provide current protection (such as overcurrent protection), voltage protection (such as overvoltage protection) and other protection functions to ensure the safe operation of the motor.

Measuring function: Can measure three phase current, zero sequence current, three phase voltage, zero sequence voltage, frequency, active and reactive power and power factor.

Control function: used to display the status information of the switchgear and realize the control of the controllable switchgear.

Condition monitoring function: including current and voltage input circuit monitoring, circuit breaker operation times counter, circuit breaker cumulative electrical wear calculation.

REM545AG228AAAA

Communication function: Support SPA, LON, Modbus and other communication protocols, easy to integrate with industrial automation system.

Fault recorder: can record the current or voltage waveform before and after the fault occurs to provide data support for fault analysis.

General functions: Provide logic control functions, such as MMI backlight activation, fixed value group switching, action signal light restoration, etc.

Designed with the harsh conditions of the industrial environment in mind, the unit has a robust construction and high protection level that enables stable performance in extreme temperature and humidity conditions. REM545AG228AAAA is used in a wide range of industrial sectors, including power generation control, oil and gas production, and water treatment.

ABB has always been committed to advancing industrial automation and digital transformation, and the launch of the REM545AG228AAAA once again demonstrates ABB’s technical strength in the field of automation and its deep understanding of customer needs. With the deepening of Industry 4.0, ABB will continue to work with customers to explore the future of smart manufacturing and provide customers with more efficient and reliable solutions.
