• Configuration B: Used for automatic voltage regulation of transformers with on-load tap changers, including three-phase non-directional overcurrent protection, overvoltage, undervoltage protection, and transformer thermal overload protection.

II. Parameters

• Rated voltage: 100–240 VAC (Configuration A) or 380–525 V (Configuration B)
• Rated frequency: 50/60 Hz ± 5 Hz
• Input current: 1/5 A
• Communication interfaces: Supports IEC 61850, GOOSE, IEC 60870-5-103, Modbus®, and DNP3, etc.
• Protection class: IP40
• Operating temperature: -20°C to +60°C
• Dimensions: 150mm × 80mm × 120mm (Configuration A) or 100mm × 150mm × 120mm (Configuration B)
• Weight: 15kg (Configuration A) or 10kg (Configuration B)

III. Product Features

• High reliability: Adopts digital protection technology to ensure stable operation under complex conditions.
• Flexible configuration: Supports two standard configurations (A and B), allowing users to select and adjust according to specific needs.
• Rich protection functions: Includes overvoltage, undervoltage, overfrequency, underfrequency, three-phase non-directional overcurrent, zero-sequence overvoltage, phase unbalance, thermal overload, etc.
• Advanced measurement functions: Supports measurement of phase voltage, zero-sequence voltage, frequency, power factor, etc.
• Powerful communication functions: Supports the IEC 61850 standard to ensure interoperability between devices.
• User-friendly interface: Equipped with a large LCD display, supporting local and remote access for easy operation and monitoring.
• Self-diagnosis function: Built-in self-check system to monitor hardware and software status in real time, preventing misoperation.

IV. Structure and Composition

• Housing: Made of high-strength plastic material with good protection performance.
• Input/output interfaces: Including phase voltage input, zero-sequence voltage input, frequency input, binary input/output, etc.
• Communication module: Supports multiple communication protocols, such as IEC 61850, GOOSE, IEC 60870-5-103, Modbus®, and DNP3, etc.
• Control unit: Responsible for processing protection, measurement, and control logic to ensure normal operation of the device.
• Human-machine interface (HMI): Provides graphical display, supporting customized single-line diagrams (SLD) and remote access.

V. Application Fields

• Power systems: Including substations, power plants, transmission lines, etc.
• Industrial distribution: Suitable for power distribution systems in industrial enterprises to ensure stable voltage and frequency.
• Renewable energy: Used for voltage and frequency protection and regulation in renewable energy systems such as wind power and solar power.
• Industrial processes: Used for equipment protection and control in industries such as manufacturing, chemical, and food processing.

VI. Installation and Maintenance

• Installation: REU615 can be quickly installed via a plug-in design, suitable for various power distribution and control cabinets. Pay attention to the connection of input/output interfaces and the configuration of the communication module during installation.
• Commissioning: Use ABB’s PCM600 tool for configuration and commissioning, supporting the creation of multi-layer logic functions.
• Maintenance: Regularly inspect the operating status of the device to ensure the cleanliness and tightness of input/output interfaces. Use ABB’s diagnostic tools for fault troubleshooting and maintenance.
