ABB RER620 Recloser Control Protection Relay

Product Overview

The ABB RER620 is a dedicated recloser control protection relay engineered for the protection, control, measurement, and supervision of utility distribution feeders and industrial power systems. It delivers dependable protection for overhead lines and cable feeders in distribution substations and is fully compatible with both grounded and ungrounded distribution networks.

Key features of the ABB RER620 include:

• Time and instantaneous overcurrent protection
• Negative sequence overcurrent detection
• Phase discontinuity monitoring
• Breaker failure protection
• Embedded loop control for automatic loop restoration
• Voltage metering and protection functions
• Drawout design for simplified maintenance and replacement
• Support for both single- and three-phase tripping to improve feeder performance
• Scalable hardware with configurable binary inputs and outputs plus multiple communication interfaces
• Recloser, switch, and sectionalizer applications configurable through the Application Configuration Tool (ACT) within PCM600
• Non-proprietary IEC 61850 communications for flexible system integration

Practical Applications

The ABB RER620 is purpose-built for recloser protection on overhead lines in distribution substations. Its embedded loop control performs automatic loop restoration, which is widely accepted as a means to significantly improve circuit reliability and deliver more effective system operation under fault conditions.

Typical use cases include:

• Protection and control of utility distribution feeders
• Supervision of industrial power systems
• Recloser applications on overhead distribution lines
• Cable feeder protection in grounded and ungrounded systems
• Sectionalizer and switch control through configurable logic
• Automatic source transfer and feeder reconfiguration

By keeping assets in service longer with compact designs that require less equipment and space, the relay reduces operating costs through effective energy management and maintenance strategies. Flexible system upgrades are possible without rewiring or component replacement, enhancing safety and overall reliability.
