About ABB REL670 SMALL PROTECTION RELAY (ONLY DISPLAY)

ABB REL670 SMALL PROTECTION RELAY (ONLY DISPLAY)

REL670 provides protection of power lines with high sensitivity and low requirement on remote end communication. Measurements and setting of all six zones with six setting groups are made completely independent, which ensures high reliability for all types of lines.

Advanced Communication and Protocol Support

The ABB REL670 relay integrates seamlessly into diverse power systems, equipped with RS232, RJ45 Ethernet, fiber optic, and USB ports. Extensive protocol compatibility-covering IEC 61850, Modbus, DNP3, and IEC 60870-5-103-ensures efficient communication with existing substation automation frameworks and enhances interoperability for modern grid requirements.


Robust Protection and Event Recording

This relay is engineered to provide comprehensive protection functions such as overcurrent, earth fault, distance, and breaker failure. Integrated event recording with time tagging and an oscillographic disturbance recorder deliver precise diagnostics and enable in-depth analysis of electrical disturbances, facilitating rapid response to system anomalies and incidents.


High Durability and Flexible Installation

Built with durability in mind, the REL670 features a compact, robust design with over 10,000 mechanical operations and IP54-rated front protection. It supports flush or panel mounting and offers both screw and plug-in terminals for reliable connections. Its wide operating temperature range and high insulation resistance make it ideal for challenging substation environments.
