Siemens Reyrolle 7SR10 Argus overcurrent and earth fault relay is a numerical overcurrent protection relay intended as a low-cost solution for distribution and industrial applications. The Reyrolle 7SR10 Argus overcurrent and earth fault relay is developed using the latest generation of hardware technology and is available in multiple variants depending on the power supply, Binary input/binary output configuration and data communication facility. Housed in a 4U high, size 4 non-draw-out case and these relays provide protection, monitoring, instrumentation, and metering with integrated input and output logic, data logging, and fault reports. Communication access to the relay functionality is via a front USB port for local PC connection or rear electrical RS485 (optional) port for remote connection.

• It has a Universal power supply suitable for both AC and DC.
• 1A and 5A CT selectable at the site: Basic communication protocols like MODBUS RTU and IEC 103 are available and they are also site selectable. Relay is equipped with a sufficient number of DI/DO i.e. up to 6 DI and 6 DO.
• Reliserv Solution offers the 7SR1003 for current-based protection, while the 7SR1004 includes additional voltage inputs to manage voltage-based protections. For motor protection applications, we provide the 7SR1005.
