ABB REJ601BD446BB1NH RELAY

The REF601 is a dedicated feeder protection and control relay. The REJ601 is an overcurrent protection relay without breaker control. These relays are intended for the protection of utility substations and industrial power systems within primary and secondary distribution networks. They are members of ABB™s Relion product family and part of its 605 series.These relays, provide 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 indepth knowledge of protection and numerical technology.The REF601 and REJ601 can be pre-configured which facilitates easy and fast commissioning of switchgear. To emphasize the simplicity of using these relays, only application specific parameters need to be set within the relay™s intended area of application. The standard signal configuration can be altered by LHMI (local human-machine interface).The relays are available in three alternative application configurations, as indicated in Table 2
