Overcurrent protection – Reyrolle 7SR10

The Reyrolle 7SR10 Argus overcurrent and earth fault relay is a numerical overcurrent protection relay intended as a simple protection solution for distribution and industrial applications.

Non-directional overcurrent protection – Reyrolle 7SR45

The Reyrolle 7SR45 Argus self-powered/dual powered non-directional overcurrent and earth fault relay is developed using the latest generation of hardware technology and is available in multiple variants depending on the current transformer (CT), binary input/binary output, power supply, and communication configuration.

Non-directional dual powered overcurrent and earth fault protection – Reyrolle 7SR46

The Reyrolle 7SR46 Argus is a dual powered non-directional overcurrent and earth fault protection device - with specific CTs. The relay is CT powered with an option for connection to an external auxiliary supply. The 7SR46 provides both definite-time and inverse-time overcurrent and earth fault protection functions.
