The following applies to the NZM PXR25:
The value range [0 - 100] corresponds to 0 to
1,000 ms, respectively, in increments of 10 ms (10

Thermal memory
(ground fault
protection)
R/W Encoded Activates/deactivates the thermal memory of the
ground-fault protection. Recommended for repe-
titive testing only. Among other things, the
thermal memory protects the switch against over-
heating during repeated overloads.
Note:
Must be reactivated after testing!
0: switched off
1: switched on

Settings - neutral
protection
R/W Unsigned Adjusts the neutral protection of an NZM PXR25
breaker with a “/VAR” variably adjustable neutral
conductor
0 = 0 %
60 = 60 %
100 = 100 % (default setting)
The lower setting affects the LSI protection func-
tions of the switch, but not the ground-fault
protection function (“G”).
Note:
L = long delay (= overload protection I
r
)
S = short delay (= short-time delayed short-circuit
protection I
sd
)
I = instantaneous (= instantaneous shortcircuit
protection I
i
)
G = ground fault (= ground fault protection I
