Description
REF601/REJ601 is a dedicated feeder
protection relay, intended for the protection of
utility substations and industrial power systems,
in primary and secondary distribution networks.
REF601/REJ601 is a member of ABB’s Relion
®
product family and part of its 605 series.
The relay provides an optimized composition of
protection, monitoring and control functionality in
one unit, with the best performance usability in
its class and are based on ABB’s in-depth
knowledge of protection and numerical
technology.

Relay functions
REF601/REJ601 offers pre-configured
functionality which facilitates easy and fast
commissioning of switchgear.
To emphasize the simplicity of relay’s usage,
only application specific parameters needs to set
within the relay’s intended area of application.
The standard signal configuration can be altered
by LHMI (local human-machine interface).
Further, the configuration functionality of the
relay supports the creation of logic functions
using various logical elements including Boolean
Logics and Timers. By combining protection
function with logic function blocks the relay
configuration can be adapted to user-specific
application requirements.
The relay is available in two alternative
application configurations, as indicated in Table
2.
