PeakTech PeakTech 2710 Digital RCD Tester
Residual current circuit breakers are used for personal protection and switch off a circuit when a fault current is detected, which flows through the protective earthing (PE). This RCD tester determines the tripping current and the tripping time of residual current circuit breakers which are used in every new building according to current building regulations. The various selectable test currents and characteristics of the FI allow flexible use of this instrument. FI testers allow a fault current to flow and determine at which fault current the FI reacts. Furthermore, the trip time is measured. These two parameters tripping current and tripping time are the safety-relevant characteristics of a residual-current-operated switch. 3-digit LCD display with backlight Normal (N) or Selective (S) -type RCD test Applicable measurement standards: IEC 61557-6, NF EN 61557-6, VDE 0413-6 Accessories: Carrying case, Test leads, Batteries and User manual Technical Specifications Nominal test current 10/30/100/500/1000mA Current selection 0.5x, 1x, 2x, 5x nominal current Trip time 10-2000 ms at 0.5 x 10-500 ms at 1x 10-150 ms at 2x 10-40 ms at 5x Ramp test 0.4 x to 1.4 times nominal rated current RCD Types Type-A, Type-AC Operation voltage 6 x 1,5 V AA (UM-3) batteries Dimensions (WxHxD) 92 x 200 x 50 mm Weight 700 g
