ABB REQ650 Protection Relay Brand New

Product Description

ABB REQ650 – Breaker Protection Relay (Relion® 650 Series)

The ABB REQ650 is a high-performance breaker protection relay from the Relion® 650 series of Intelligent Electronic Devices (IEDs). It is engineered for comprehensive protection, control, and monitoring of circuit breakers in both distribution and transmission substations. As a factory-tested, pre-configured solution, the REQ650 simplifies deployment while offering high-speed backup tripping and advanced breaker failure protection, making it an ideal choice for modern and retrofit substations.

Key Features

• Comprehensive Breaker Protection:
  Includes instantaneous phase overcurrent, directional phase/residual overcurrent, thermal overload, breaker failure protection, stub protection, and pole discordance protection.

• High-Speed Backup Tripping:
  Enables fast backup tripping of adjacent breakers and re-tripping of the protected breaker in case of failure—essential for reliable substation operation.

• IEC 61850 Compliance:
  Fully supports IEC 61850, including GOOSE messaging, for seamless digital substation integration and future-proof interoperability.

• User-Friendly HMI:
  Features an extended front-panel interface with a large display showing single-line diagrams, live measurements, and customizable three-color LED indicators (up to 15 per page across three pages).

• Pre-Configured Parameters:
  Delivered with pre-set default configurations, minimizing commissioning effort and reducing parameter setting complexity.

• Self-Supervision:
  Incorporates built-in self-monitoring, including analog channel supervision, ensuring high availability and diagnostic capability.

• Flexible Communication Options:
  Supports IEC 61850, Modbus, Ethernet, SNTP, DNP 3.0, IEC 60870-5-103, and IRIG-B for time synchronization.

• Versatile Substation Use:
  Applicable to various configurations including single and double busbars, and compatible with both three-phase and single-phase tripping schemes.

• Rugged Industrial Design:
  Compact, robust construction built for long-term operation in harsh environments.

• Ideal for Refurbishment:
  A smart upgrade path for modernizing legacy systems by replacing outdated protection relays.
