ABB SUE3000 1VCR007346 G0028: Electric Motor Protection Relay
Product Description
The
ABB SUE3000 1VCR007346 G0028 is a sophisticated microprocessor-based protection relay designed for the comprehensive monitoring and safeguarding of electric motors in industrial applications. Part of the SUE3000 product line, this device integrates multiple protection functions, metering capabilities, and communication features into a single unit. The primary role of the
is to prevent motor damage by detecting faults such as overload, phase loss, unbalance, locked rotor, ground faults, and jam conditions. By providing reliable protection, it enhances system safety, reduces downtime, and extends the operational life of critical motor-driven assets. As an intelligent electronic device, the
ABB SUE3000 1VCR007346 G0028 also serves as a data source for condition monitoring and energy management systems. Its robust design is suitable for direct panel mounting in demanding environments.

Advantages and Features
The key advantage of the is its combination of advanced protection algorithms and user-friendly operation. It features a highly accurate thermal replica model that tracks motor heating and cooling, providing optimal overload protection and allowing for safe motor restart. The relay offers extensive programmability, allowing each protection function to be finely tuned to the specific motor and application. Its integrated communication capabilities enable remote monitoring of motor status, load currents, thermal capacity used, and fault logs, facilitating predictive maintenance. The compact yet feature-rich design of the ABB SUE3000 1VCR007346 G0028 reduces panel space and wiring compared to using multiple discrete protection devices.
Application Cases in Various Fields
This relay is essential for protecting motors across all industries. In
Water/Wastewater Treatment, the
protects critical pumps and blowers from dry-running (jam) and overload. Within
Mining and Minerals, it safeguards crusher motors, conveyor drives, and slurry pumps from unbalanced loads and mechanical jams. For
HVAC Systems in large buildings, it protects chilled water pumps and cooling tower fans. It is widely used in
Manufacturing to protect motors on machine tools, compressors, and material handling systems. In
Oil & Gas, it ensures the reliability of motors driving pipeline pumps and compressor auxiliaries.
Comparisons with Competing Products
Compared to basic thermal overload relays or simpler electronic protectors, the ABB SUE3000 1VCR007346 G0028 offers a far superior level of intelligence, diagnostics, and connectivity. When compared to motor protection relays from competitors like Siemens (SIRIUS 3RU/3RB) or Schneider Electric (TeSys), the ABB solution is often recognized for its intuitive configuration, robust thermal modeling, and strong integration with ABB’s own variable speed drives and control systems. Its value proposition lies in moving from simple fault reaction to advanced motor management, providing data that helps optimize performance and prevent failures before they occur.
Selection Suggestions and Precautions
- Motor Specifications: To configure the correctly, you must have the motor’s full load current (FLC), service factor, and starting characteristics (e.g., cold/hot stall times) from the motor nameplate and data sheet.
- CT Selection: Choose current transformers (CTs) with a ratio appropriate for the motor’s FLC. The relay’s input range must match the CT’s secondary output (typically 1A or 5A).
- Communication Planning: If using the communication interface, plan the network addressing (Modbus slave ID) and ensure the protocol and baud rate match the master device (e.g., PLC or SCADA).
- Functional Testing: After installation and configuration, perform a thorough functional test. Simulate key alarm conditions (like phase loss) to verify the ABB SUE3000 1VCR007346 G0028 operates the trip/output relays as designed in your safety circuit.
- Parameter Backup: Once the relay is correctly configured for your motor, document all settings and, if possible, use the relay’s software tools to create a backup parameter file. This is crucial for quick recovery in case of a device failure.
