7SR10 Description of OperationSection 1: IntroductionThis manual is applicable to the following relay: 7SR10 Overcurrent RelayGeneral Safety Precautions1.1!1.2!1.3Current Transformer CircuitsThe secondary circuit of a live CT must not be open circuited. Non-observance of this precaution canresult in injury to personnel or damage to equipment.External ResistorsWhere external resistors are connected to the relay circuitry, these may present a danger of electricshock or burns, if touched.DescriptionThe 7SR10 Overcurrent relay is developed by using the latest generation of hardware technology and is availablein multiple variants depending on power supply, binary input/output configuration, voltage input, and datacommunication facility. 7SR10 is a member of Siemens Reyrolle protection devices Argus product family.The 7SR10 overcurrent relay consists of non-directional functions and with additional voltage inputs providingdirectional functions (based on the ordering option).The 7SR10 Overcurrent relay is housed in a 4U high, size 4 non draw-out case and these
