ABB REG630 Generator Protection and Control Relay
ABB REG630 Generator Protection and Control Relay Supplier and Exporter in India
ABB REG630 Legacy Supply and Replacement Enquiries
ABB REG630 is a generator protection and control relay used for small and medium-sized generators and generator-transformer units. For price and availability, send the complete order code, relay nameplate, quantity and destination country.
Description
ARP IMPEX supplies and exports ABB REG630 generator protection and control relays for power plants, captive generation systems and existing Relion 630-series installations.
REG630 belongs to ABB’s Relion 630 series and was developed as the main protection relay for small and medium-sized generators and generator-transformer units. It combines generator protection, control, measurement and supervision in one relay.
The protection functions cover many of the faults and operating conditions normally associated with generators. These include generator differential protection, reverse power, loss of excitation, overcurrent, negative-sequence current, voltage and frequency protection. REG630 also supports stator and rotor earth-fault protection, with additional transformer differential protection available for generator-transformer applications.
REG630 can also be used where a generator operates in parallel with the grid. Functions for frequency, voltage, reactive power and interconnection protection help supervise the generator connection to the network.
For ABB REG630 price, availability or replacement enquiries, send the complete ABB part number and a clear photograph of the relay nameplate. The product version and order code are important because the I/O and analogue input arrangements can differ.

The exact I/O arrangement depends on the ordered REG630 hardware. ABB documentation shows several analogue-input and binary-I/O combinations, so the full order code should be checked for a matching unit.
Features
- Generator differential protection
- Reverse power protection
- Loss-of-excitation protection
- Stator earth-fault protection
- Rotor earth-fault protection
- Negative-sequence protection
- Generator thermal overload protection
- Overcurrent and earth-fault protection
- Overvoltage and undervoltage protection
- Overfrequency and underfrequency protection
- Rate-of-change-of-frequency protection
- Generator-transformer differential protection where configured
- Circuit-breaker failure protection
- Disturbance and event recording

- IEC 61850 communication and GOOSE messaging
The fitted functions depend on the REG630 configuration. For an existing relay, the order code and configuration details give a clearer picture than the model name alone.
Applications
ABB REG630 is used for:
- Small power generators
- Medium-sized generators
- Synchronous generator protection
- Generator-transformer units
- Captive power plants
- Industrial generating stations
- Hydro power generation
- Diesel generator plants
- Steam turbine generator installations
- Generator differential protection
- Generator stator earth-fault protection
- Reverse power protection
- Loss-of-excitation protection
- Generator interconnection protection
- Distributed generation connected to the grid
ABB describes REG630 as the main protection relay for generators and generator-transformer units in utility and power-distribution systems.
ABB REG630 Configuration
Unlike some other 630-series relays with several predefined application configurations, REG630 documentation identifies one main factory preconfiguration.
ABB REG630 Preconfiguration A
Preconfiguration A is intended for a directly connected generator set.
It includes the core generator protection functions and can be modified through ABB PCM600 according to the generator and protection scheme.
ABB REG630 Without Preconfiguration
REG630 could also be ordered without a factory preconfiguration for projects where the complete protection logic was to be built specifically for the generator application.
ABB allows the protection functions, alarms, HMI indications, communication and logic to be adapted through PCM600.
For a replacement enquiry, send the original REG630 order code and configuration information whenever available.
ABB Relion 630 Series
ABB’s Relion 630 protection and control range includes:
- ABB REF630 – Feeder protection and control
- ABB REM630 – Motor protection and control
- ABB RET630 – Transformer protection and control
- ABB REG630 – Generator protection and control
REG630 is the generator-focused model in the series and was introduced with the later 630-series product versions.
ABB REG630 Replacement
ABB’s 630-series lifecycle notice identifies REX640 as the replacement product for REG630 versions 1.2 and 1.3. ABB also notes that another current Relion product may be selected depending on the particular application.
For an ABB REG630 replacement enquiry, please send:
- Complete ABB REG630 order code
- Product version, if available
- Clear relay nameplate photograph
- Quantity
