WebSep 5, 2024 · What is the maximum allowable tripping time? A common misconception is that RCDs must trip in 30 ms. In fact, an RCD when tested at its rated sensitivity must trip in 300 ms. When tested at five times, ie, 150 mA for a 30 mA device, it should trip in 40 ms. WebA residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that quickly breaks an electrical …

All the certificates I use have two RCD trip time columns, one for x1 and one for x5, bearing in mind if your tester has an auto sequence to fully test RCDs, x0.5 from 0degrees and 180degrees, x1 from 0degrees and 180degrees, x5 from 0degrees and 180degrees.
http://powerquality.sg/wordpress/?p=622 WebHowever, if it did pretest at half current then the 30mA RCD would trip at 25mA as that is over the ramp test result of 22mA at 0 and 24mA at 180. It even worked at 55mA without tripping and that would have been 27.5mA if it was half. It did trip, though, set at 60mA, displaying "trp" so must have pretested at over 22/24mA.
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 …
