Auxiliary Switch Z-HK, Z-AHK; Tripping Signal Switch Z-NHK
• Design according to IEC/EN 60947-5-1, IEC/EN 62019
• Can be mounted subsequently (screws)
• The specified minimum voltages are per contact
Take into account particularly in case of series connection!
• Z-AHK, Z-NHK: Contact function with relative movement (self-cleaning contacts)
• Contact material and design particularly suitable for extra low voltage
• Z-NHK: The function of one of the two change-over contacts can be
switched from “auxiliary switch” to “tripping signal switch”
• Tripping signal contact transmits message of electric tripping, not mechanical switch-off
• Test key for contact function “electrical tripping”

The specified minimum voltages are per contact. Take into account particularly in case of series connection!
Contact material and design particularly suitable for extra low voltage.

ZP-NHK: The function of one of the two change-over contacts can be
switched from “auxiliary switch” to "tripping signal switch"

ZP-IHK
ZP-WHK
ZP-NHK
• ZP-NHK: The “Service button” is used to check whether or not the auxiliary switch is correctly wired in the tripping-signal-switch position. Activating the “service button” will
mechanically simulate an electrical switch-off, so the mechanism for the electrical switchoff will disengage and can be checked.
The main switchgear (MCB, combined MCB/RCD or RCD …) connected to the ZP-NHK auxiliary switch does not need to trip as well during an inspection through the service button.
