NZM Auxiliary Contact Notes

Switching with the main contacts Used for indicating and interlocking tasks Can be clipped into the circuit-breaker when used as standard auxiliary contact

NZM1, N(S)1, PN1- one standard auxiliary contact

NZM2, N(S)2, PN2 - up to 2 standard auxiliary contacts

M22-(C)K...

NZM3, N(S)3, PN3 and NZM4, N(S)4 - up to 3 standard auxiliary contacts M22-(C)K... Any combinations of the auxiliary contact types is possible.

Marking on switch: HIN Can be clipped into the circuit-breaker when used as tripped auxiliary contact

NZM1 - one trip-indicating auxiliary switch

NZM2 - one M22-(C)K... trip-indicating auxiliary switch

NZM3 - one M22-(C)K... trip-indicating auxiliary switch

NZM4 - up to 2 M22-(C)K... trip-indicating auxiliary switches Not in combination with switch-disconnector PN... Any combinations of the auxiliary contact types is possible. Marking on switch: HIA Labeling in FI-Block: HIAFI. If the trip-indicating auxiliary contact in the fault-current block is used, the N/C contacts operates as a N/O contact and the N/C contact operates as an N/O contact (circuit symbol)
