The ABB REU615E_D HBUAEAADNCA1BNN1XD is a member of the ABB Relion® family of voltage protection and control devices in the 615 family. Designed for utility and industrial power distribution systems, including grids with distributed generation, this unit provides a compact and versatile solution.

The REU615 device is available in two standard configurations, Standard A and Standard B. Standard Configuration A is suitable for applications such as busbar low and overvoltage monitoring, load rejection (cut-off) and load recovery (reconnection), as well as overfrequency and low frequency protection for generators and other AC equipment. Standard configuration B is suitable for manual or automatic voltage regulation with electric on-load regulator switch transformers.

The key benefits of this voltage protection measurement and control unit include voltage and frequency protection with automatic on-load regulation, automatic and manual regulation, and pre-configured standard configurations that can be configured quickly and easily to meet different application requirements. The REU615 also features a pluggable design for quick installation and testing with a large LCD display with editable single-line charts that can be accessed locally or via an easy-to-use Web browser-based HMI.
