ABB REM630 Motor Protection and Control Relay
ABB REM630 Motor Protection and Control Relay Supplier and Exporter in India
ABB REM630 Legacy Supply, Replacement and Motor Protection Enquiries
ABB REM630 is a motor protection and control relay used for medium and large synchronous and asynchronous motors. For price and availability, send the complete ABB order code, relay nameplate, quantity and destination country.
Description
ARP IMPEX supplies and exports ABB REM630 motor protection and control relays for industrial motor feeders, existing switchgear and motor control applications.
REM630 belongs to ABB’s Relion 630 series and is used for protection, control, measurement and supervision of medium and large motors. It can be applied to both synchronous and asynchronous motors and works with circuit-breaker-controlled as well as contactor-controlled motor feeders. ABB lists applications such as pumps, fans, compressors, mills and crushers.
The relay covers the main conditions that need to be watched during motor starting and normal operation. These include thermal overload, long starting time, locked rotor or load jam, phase unbalance, phase reversal, loss of load, overcurrent and earth fault. Voltage-related protection is also included in the standard motor configurations.
REM630 was supplied with different hardware and I/O combinations, so an enquiry should include the full ABB order code and nameplate photograph rather than only the REM630 model name.
For ABB REM630 price, spare availability or replacement enquiries, send the relay code, quantity and destination country to ARP IMPEX for checking and quotation.

The exact functions depend on the ordered REM630 configuration, which is why the relay code is important when checking an existing unit.
Applications
ABB REM630 is used for:
- Medium-voltage motor protection
- Large asynchronous motors
- Large synchronous motors
- Pump motors
- Fan motors
- Compressor motors
- Mill motors
- Crusher motors
- Process plant motor drives
- Mining and mineral-processing motors
- Cement plant motor applications
- Oil and gas motor feeders
- Industrial motor control panels
- Circuit-breaker-controlled motors
- Contactor-controlled motors
- Motor feeders requiring differential protection
ABB describes REM630 as the main protection for medium and large synchronous and asynchronous motors and specifically identifies pump, fan, compressor, mill and crusher drives among its applications.
ABB REM630 Configurations
ABB supplied REM630 with two main predefined motor configurations.
ABB REM630 Preconfiguration A
Configuration A is intended for asynchronous motor protection.
It includes the main motor functions such as:
- Thermal overload
- Motor start supervision
- Load jam protection
- Loss of load
- Overcurrent
- Earth fault
- Phase unbalance
- Phase reversal
- Voltage supervision
ABB REM630 Preconfiguration B
Configuration B is also intended for asynchronous motors but adds stabilised motor differential protection.
This version is relevant where differential protection is required in addition to the standard REM630 motor-protection functions.
ABB also allows REM630 to be ordered without a predefined application configuration for projects requiring a customised setup.
For an existing relay, send the complete order code so the A, B, or customised configuration can be identified correctly.
ABB Relion 630 Series
ABB’s 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
REM630 is specifically built around motor protection and motor feeder control.
ABB REM630 Replacement
ABB’s 630-series lifecycle notice identifies REX640 as the replacement product for REM630 versions 1.1, 1.2 and 1.3. ABB also notes that other current Relion products can be considered depending on the application.
For an ABB REM630 requirement, please send:
- Complete REM630 order code
- Product version, if available
- Clear nameplate photograph
- Quantity
- Destination country
- Required delivery date
If the requirement involves replacement rather than an identical spare, the existing motor application and configuration details can be checked after the relay has been identified.
