Product Description

The ABB REG630 is a multifunction generator protection and control IED designed for small and medium-sized generators and generator-transformer units. It integrates protection, control, measurement, monitoring, and supervision functions in one device. The REG630 supports generator differential protection, stator earth-fault protection, reverse-power protection, interconnection protection, and a range of voltage, current, frequency, and backup protection functions. Depending on the configured hardware and software, it supports IEC 61850 Edition 1 with GOOSE, DNP3 TCP/IP, and IEC 60870-5-103 communication. ABB currently identifies REG630 as a product that has not been active since 2024, making exact configuration and replacement compatibility important for existing installations.

FAQ

Q: What is the ABB REG630?

A: REG630 is a Relion 630-series generator protection and control IED designed as the main protection and control device for generator and generator-transformer units.

Q: What protection functions does REG630 provide?

A: Depending on configuration, functions include generator differential protection, third-harmonic stator earth-fault protection, reverse-power protection, overcurrent, voltage, frequency, negative-sequence, and backup protection.

Q: Which communication protocols are supported?

A: The REG630 supports IEC 61850 Edition 1, including GOOSE messaging, as well as DNP3 TCP/IP and IEC 60870-5-103.

Q: Can the REG630 be freely configured?

A: The 630-series architecture uses configurable hardware and software modules. ABB’s ordering information shows that the final order code is generated from the selected hardware and software configuration, so two REG630 units may not have identical I/O or communication arrangements.

Q: Is the REG630 discontinued?

A: ABB’s current product page states that REG630 has not been an active product since 2024. Existing-system replacement should therefore be based on the complete ordering code, hardware configuration, firmware requirements, and application.
