Description
Product Overview
The ABB REB611 is a dedicated busbar protection and control relay engineered for phase-segregated short-circuit protection in modern utility substations and industrial electrical networks. As part of the Relion® 611 series, it offers reliable high-impedance busbar protection and advanced earth-fault detection for generators, motors, transformers, and reactors.
Designed with a strong focus on operational reliability and ease of deployment, the REB611 arrives with a preconfigured application package that significantly reduces engineering and commissioning time. Its compact footprint and plug-in design make it suitable for both new installations and retrofit upgrades within ABB’s COMBIFLEX system environment.
