ABB REF630 Feeder Relay – Legacy Supply and Replacement Enquiries

ABB REF630 is a feeder protection and control relay for overhead lines, cable feeders and feeder bay applications. For price and availability, send the complete order code, relay nameplate, quantity and destination country.

Description

ARP IMPEX supplies and exports ABB REF630 feeder protection and control relays for utilities, industrial distribution systems, substations and existing Relion 630-series installations.

REF630 is part of ABB’s Relion 630 series. It was developed for protection, control, measurement and supervision of distribution feeders and can be used on radial, looped and meshed networks, including networks with distributed generation. It can also handle feeder bay control from the same relay.

REF630 covers phase overcurrent, directional overcurrent and several earth-fault protection methods. Depending on the configuration, it can also provide voltage protection, autoreclosing, synchro-check, breaker failure protection, fault location and power-quality monitoring. ABB gave particular attention to earth-fault protection in the 630 series, including directional, intermittent/transient, admittance-based and multi-frequency admittance-based functions.

The relay was supplied with several predefined feeder configurations, so the exact REF630 version and order code are important when checking an existing unit.

For ABB REF630 price, spare availability or replacement enquiries, send us the complete part number and a clear nameplate photograph.

Applications

ABB REF630 is used for:

• Medium-voltage feeder protection
• Overhead distribution lines
• Cable feeder protection
• Radial distribution feeders
• Ring-main networks
• Meshed distribution systems
• Incoming feeder protection

ABB identifies REF630 as the main protection for overhead lines and cable feeders in utility and industrial distribution systems.

ABB REF630 Preconfigurations

REF630 was available with predefined application configurations that could be further adapted through PCM600.

REF630 Configuration A – Ring Feeder

Used for open or closed ring feeder applications.

REF630 Configuration B – Radial / Mixed Line Feeder

Intended for radial overhead lines and mixed overhead/cable feeders.

REF630 Configuration C – Ring / Meshed Feeder

Used where the distribution system has ring or meshed network arrangements.

REF630 Configuration D – Bus Sectionalizer

Intended for bus-section protection and control. ABB also offered an option without a predefined application configuration for projects requiring a more customised setup.

For a matching REF630 requirement, send the complete ABB order code because the preconfiguration, analogue inputs and binary I/O are identified through the ordered variant.

ABB Relion 630 Series

The ABB 630 protection and control series covers four main relay types:

• ABB REF630 – Feeder protection and control
• ABB REM630 – Motor protection and control
• ABB RET630 – Transformer protection and control
• ABB REG630 – Generator protection and control

Although they share the same 630-series platform, each relay is built around a different primary protection application.

ABB REF630 Replacement

ABB’s lifecycle notice identifies REX640 as the replacement product for REF630 versions 1.1, 1.2 and 1.3. ABB also notes that other Relion products may be considered depending on the application.

For an existing REF630 requirement, please send:

• Complete ABB REF630 order code
• Relay version, if available
• Clear nameplate photograph
• Quantity
• Destination country
• Required delivery date

For replacement projects, the existing protection configuration and I/O details may also be required after the installed relay has been identified.
