Protective Devices Residual Current Devices - General Data Short description of the most important RCD types: Symbol Description Trip also at frequency composition (10 Hz, 50 Hz, 1000 Hz) Type B+: All-current sensitive RCD switchgear for applications where DC fault currents may occur. Non-selective, non-delayed. Protection against all kinds of fault currents. Also meets the requirements of the VDE 0664-400 standard (formerly known as VDE V 0664-110) and therefore provides enhanced fire safety. T CD of type G (min 10 ms time delay) surge current-proof up to 3 kA. For system components...

Protective Devices Hints for the application of our frequency converter-proof RCDs: Due to the currents ﬂowing off through the ﬁlters (designated IF), the sum of currents through the RCD is not exactly zero, which causes unwanted tripping. Screened motor line Mains side ﬁlter Frequency converter Frequency converter Mains-side ﬁlter Mains-side ﬁlter Frequency converters are used in a wide variety of systems and equipment requiring variable speed, such as lifts, escalators, conveyor belts, and large washing machines. Using them for such purposes in circuits with conventional residual current...
