Overview
The ABB REQ650 is a dedicated breaker protection relay that ensures fast and reliable backup tripping in case of breaker failure. It is engineered for high-voltage substations and industrial power systems where selective fault isolation is critical. Moreover, the REQ650 supports re-tripping of its own breaker and tripping of adjacent breakers to maintain system stability. Its ready-made configuration and reduced parameter settings simplify commissioning and reduce engineering time. In addition, the device features dynamic LEDs, graphical display, and remote access capabilities for enhanced usability and diagnostics.

Typical Applications
The REQ650 is widely used in substations for local backup protection of circuit breakers. It ensures that faults are isolated quickly if a primary breaker fails to operate, preventing cascading outages. For instance, utilities deploy REQ650 in transmission and distribution substations to enhance system reliability. In addition, it integrates seamlessly with ABB’s substation automation systems and SCADA platforms via IEC 61850. Its modular design and flexible logic functions make it ideal for retrofit projects and new installations alike.
