Product Description

Siemens Reyrolle 7SR10 Overcurrent Numerical Relay

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 Universal power supply suitable for both AC and DC.
  • 1A and 5A CT selectable at site: Basic communication protocol like MODBUS RTU and IEC 103 available and they are also site selectable. Relay are equipped with sufficient number of DI/DO i.e. upto 6 DI and 6 DO.
  • 7SR1003 is designed for current based protection and 7SR1004 is available with additional voltage inputs to take care of voltage based protections. 7SR1005 is designed for motor protection application.
