Notes

With I△n = 0.03 A: delay time tv always fixed setting at 10 ms.

Alarm message > 30 % I△n by yellow LED.

Trip indication max. 2 auxiliary contacts (HIAFI) can be fitted by user: N/O = M22-K01, N/C = M22-K10 are reset via the reset toggle lever.

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.

Double contact not permissible.

Not in combination with insulated enclosure or main switch assembly kit for side panel mounting with mounting bracket

NZM1-XFI...R can not be used in combination with lower cover NZM1-XUSA.

NZM1-XFI…U not in combination with shunt or undervoltage release, early-make auxiliary contacts.

Rated ultimate short-circuit breaking capacity is determined by the fitted NZM1, NS1.

If a switch-disconnector N1 is applied by the back-up fuse to be used → Technical data.
