ABB REU610 Voltage Protection Relay
ABB REU610 Voltage Protection Relay Supplier and Exporter in India
ABB REU610 Legacy Spare, Replacement and REX615 Retrofit Enquiries
Replacement: ABB REU610 is a legacy voltage protection relay and has not been active since 2017. ABB includes REU610 in its official 610-series to REX615 retrofit program.
Description
ARP IMPEX supplies and exports ABB REU610 voltage protection relays for voltage supervision, existing switchgear, substations and industrial power systems.
REU610 belongs to ABB’s Relion 610 series and is used for system voltage protection, measurement and supervision. Typical duties include overvoltage and undervoltage protection of distribution substation busbars, feeder and transformer overvoltage protection, motor undervoltage protection and capacitor-bank supervision.
The relay provides two-stage overvoltage, two-stage undervoltage and two-stage residual overvoltage protection. Depending on the selected function, REU610 can also provide negative phase-sequence overvoltage or positive phase-sequence undervoltage protection.
In isolated-neutral systems, REU610 can use residual voltage measurement for earth-fault supervision. ABB also documents the relay for automatic busbar changeover initiation and for disconnecting small generating units from the public network during islanding conditions.
For ABB REU610 price and availability, send the complete order code, a clear relay nameplate photograph, quantity and destination country. The complete part number helps confirm the correct hardware and communication arrangement before quotation.

ABB Relion 610 Series
ABB’s 610 series includes three main relay types:
ABB REF610
A feeder protection relay used for incoming and outgoing feeder protection.
ABB REM610
A motor protection relay used for protection and supervision of asynchronous LV and HV motors.
ABB REU610
A voltage protection relay for overvoltage, undervoltage, residual voltage and general system voltage supervision.
The three products share the 610-series platform but perform different protection duties.
ABB REU610 Replacement and REX615 Retrofit
ABB includes REU610 in its official Relay Retrofit Program for REF610, REM610 and REU610 to REX615. The retrofit package includes a REX615 relay with the required retrofit connector kit and documentation.
ABB developed the program to replace supported 610-series relays without major new panel wiring and to reduce shutdown work during the changeover.
For an ABB REU610 replacement or REX615 retrofit enquiry, send:
- Complete REU610 order code
- Clear relay nameplate photograph
- Required quantity
- Destination country
- Required delivery date
Panel and configuration details can be checked if the requirement involves a retrofit rather than an identical legacy spare.
