REF601 ABB Feeder Protection and Control Relay

Introducing the ABB REF601 Feeder Protection and Control Relay, a cutting-edge solution designed to ensure the safety and efficiency of your electrical systems. This high-performance relay is built to protect and control feeders, offering a wide range of features that cater to various industrial and commercial applications.

Key Features and Specifications

The REF601 is equipped with an array of technical specifications that make it a reliable choice for any electrical network. With a nominal voltage range of 24...240 V AC/DC and a current input of 1 A or 5 A, this relay can handle diverse electrical loads. Its thermal withstand capability allows continuous operation at 4 A or 20 A, while dynamic current withstand capabilities ensure protection against short circuits and overloads. The input impedance is less than 100 mΩ or 20 mΩ, ensuring minimal signal loss and optimal performance.

Advanced Protection and Control Functions

The REF601 offers comprehensive protection and control functionalities. It includes non-directional overcurrent protection, ground-fault protection, phase discontinuity protection, negative sequence overcurrent protection, and circuit breaker failure protection. These features ensure the safety of your electrical system by detecting and responding to potential faults promptly. Additionally, the relay provides control functionality, allowing for local HMI operations for opening and closing breakers. Measurement capabilities include three-phase current, residual current, negative phase sequence current, and thermal level, providing valuable insights into the health of your system. Event logging and fault recording further enhance the relay's functionality, allowing for easy troubleshooting and maintenance.
