■Benefits • UC sensitive: For detection of AC fault currents, pulsating and smooth DC residual currents • Time-saving wiring and simplified device coordination thanks to RCBO for combined personnel and line protection in a single device • Increased operating safety in systems with capacitive impedances due to adapted tripping characteristic • Additional components can be retrofitted by the customer • External remote tripping with terminals Y1/Y2.
■Application • Systems with equipment in which smooth DC residual currents can also arise (e.g. with B6 bridge circuit on frequency converters and medical equipment) • Product standards: IEC/EN 61009-1 (VDE 0664, Part 10); VDE 0664 Part 200; IEC/EN 61543 (VDE 0664, Part 30) • For use in 3-phase current systems • Un = 400 V or Un = 480 V; 50 ... 60 Hz • Definition of surge current withstand capability with current waveform 8/20 μs according to DIN VDE 0432 Part 2 • æ K type, super-resistant: short-time delayed tripping in the case of transient leakage currents. High surge current withstand capability: > 3kA.
