ABB REU610 Voltage Relay In Stock Ready to Ship

Voltage relay REU610 REU610 is a voltage relay for system voltage protection, measurement and supervision in utility and industrial power systems.

Not active product since 2017

REU610 is a member of ABB’s Relion^® product family and part of its 610 product series. The series includes protection relays for feeder protection, motor protection and general system voltage supervision. The plug-in design facilitates the commissioning of the switchgear and enables fast and safe insertion and withdrawal of plug-in units.

REU610 is designed for distribution substation busbar over-voltage and under-voltage protection, feeder and power transformer over-voltage protection, motor under-voltage protection, and capacitor bank protection and supervision. In isolated neutral power systems, it is also used for non-discriminative earth-fault protection, based on residual voltage measurement. REU610 is used for initializing automatic substation busbar changeover and for disconnecting small power units from the public network, that is, islanding.

Scope

Voltage protection relay

Product benefits

The compact design makes it suitable for both new and retrofit installations
Quick and easy routine maintenance thanks to the removable plug-in design
Complete type test certified by KEMA
Certificated for marine and off-shore use by Det Norske Veritas (DNV)

Product features

Protection for utility distribution and basic industrial applications
REU610 offers integrated protection functions including two-stage overvoltage protection, two-stage undervoltage protection and two-stage residual overvoltage protection. Furthermore, REU610 includes two mutually exclusive protection functions, a single-stage negative phase-sequence overvoltage protection function or a single-stage positive phase-sequence undervoltage protection function.
REU610 supports a wide range of standard communication protocols, including IEC 61850, IEC 60870-5-103, Modbus®, Profibus, DNP3, SPA and LON.
