Penerangan
Product Description
The ABB REJ603BBB10NN3XC is a self-powered feeder protection relay engineered for medium-voltage secondary distribution networks. Unlike traditional relays, it derives operating power directly from the current transformer (CT) input, eliminating the need for an auxiliary power source. This design makes it ideal for applications where external power is limited, such as ring main units (RMUs), compact substations, and distribution automation projects.
