WebMay 24, 2024 · All RCCBs subjected to 50Hz AC residual current are designed to trip between 0.5-1I∆n. Type A,F,B: Pulsed residual current (50Hz), the tripping threshold changes to 0.35-1.4I∆n. Type A & F: Trip threshold is influenced by the smooth DC content (offset value) e.g. Type A must still trip with < 6mA smooth DC superimposed on the pulsed … Web1 x In = 300ms. 2 x In = 150ms. 5 x In = 40ms. 'In' is the symbol given to tripping current - so, for example, 2 x In of 30mA = 60mA. RCDs used in commercial and industrial environments have higher mA ratings of 100mA, 300mA and 500mA. 3.
