Which type of residual current device (RCD) you should use for
WebRCD 2 type RC222 : Installed, for example, on Tmax T5: RCD 3 type RCQ : Installed, for example, on Emax E2.2 : characterized by the curves shown in the following time-current diagram. It can be seen how overlapping of the curves of the three devices used is avoided, thereby obtaining selectivity in case of earth fault. WebDifferent RCDs are given a waveform classification to help people identify what type of current an RCD can detect. The following classifications are given according to the waveform of earth leakage currents: Type A – ideal for circuits using AC and DC power. Type AC – trip on sinusoidal residual current. Type B – respond to higher ... WebVollständige Typ F Funktionalität. + Erkennung glatter Gleichströme, hochfrequente Ströme bis zu 2 kHz, hohe Anlagenverfügbarkeit.
