A9Z61440 RCD, sensitive to all currents, 4P, 40A, type B-SI, 30 mA

RCD, sensitive to all currents, Acti 9 iID.

4-pin Nominal current 40A Type B-SI Rated residual current 30 mA Operating voltage (UE) 400 AC/50 Hz Isolation voltage 500 V AC

Jump circuit for low-wear contact switching. With mechanical, front-side error message display (VisiTrip) for displaying tripping due to residual current. Safe contact display (VisiSafe) of the RCD, with green indicating the safe absence of voltage on the outgoing side. Test button for regular function testing. Double terminals for connecting cables or phase rails on both sides. Easy removal of the individual device with the phase rail installed thanks to the front-accessible fastening element. Additional stackable auxiliary modules (optional): under-voltage release (iMN), over-voltage release (iMSU), shunt release (IMX), auxiliary switch for status message (iOF), auxiliary fault contact (iSD). Type B-SI is integrated with SI technology, which offers higher resistance to electrical interference. Protects against smooth DC residual currents in 1- or 3-phase power supply systems caused by frequency converters, inverters and emergency power supplies. Colour RAL 9003. Complies with the following standards IEC/EN 61008-2-1, IEC/EN 62423, IEC 61543, VDE 0664. RCD for power distribution boards.
