ABB Relion REJ603

A self-powered protection relay for the protection of utility substations and industrial power distribution systems in secondary distribution.

ABB Relion REJ603

 
ABB Relion REJ603 is a self-powered protection relay for the protection of utility substations and industrial power distribution systems in secondary distribution. It is a current-transformer-powered protection relay for applications where auxiliary power is not available or cannot be guaranteed. An ideal choice for installation at remote locations. The relay is often used in ring main units and secondary distribution switchgear within distribution networks.  
 

ABB Relion REJ603 leverages the same configuration software as all ABB Relion protection and control products. ABB’s protection relays are available for original equipment manufacturers (OEM), panel builders and Engineering, Procurement and Construction (EPCs) partners to incorporate in their own installations or for use in new, retrofit or upgrade projects.
