Sepam 2000 - Schneider Electric

Selection of SW1 and SW2(microswitches) operatingmodesThe operating mode is selected by settingthe microswitches on the rear of the device.They must be set before Sepam 2000 is switched on,while it is de-energized.Set microswitches SW1 and SW2 in accordancewith he chart opposite. They are to be setaccording to:b the CSP model used (30 A-300 A, 160 A-1600 A,500 A-2500 A),b the rated current of the protected installation,b the earth fault current measurement method(sum or core balance CT).N.B. When the rated current of the electricalinstallation to be protected does not appearin the chart, choose the column that correspondsto the current rating immediately above.Example of microswitch settingThis example indicates the microswitch settingin the following case:b network rated current: 160 A,b CSP sensor used: model 160-1600 A,b residual current measured by the sumof the 3 phase currents.Microswitch setting chartCSP 31-10: 30 to 300 A30 36 45 60 75 90 120 150 180 225 300CSP 32-10: 160 to 640 and CSP 33-10: 160 to 1600 A160 192 240 320 400 480 640 800 960 1200 1600CSP 34-10: 500 to 2500 A500 600 750 1000 1250 1500 2000 2500SW2 : for selection of the phase current range0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 10 11phase 167SW1: residual current by the sum of the 3 phase currentsSOM 1 SOM 20 1 0 1 0 1 0 1 0 1 0 1 0 10 1 0 10 10 1phase 2phase 31213SW2SW1: residual current measured by core balance CT0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 10 10 10 11812 SW1SOM 1 and SOM 2 are parameters to be set in the status menu of the pocket terminal.HV/MV substation Installation - Use - Commissioning1/13
