(overload protection)
R/W

Activates/deactivates the thermal
memory of the overload protection.
Recommended for repetitive testing only.
Among other things, the thermal memory
protects the switch against overheating
during repeated overloads. Reactivate
the thermal memory after testing:

ZSI
R/W
Encoded
ZSI, zone-selectivity:
If enabled for releases with ground-fault
protection, ZSI is implemented for both
the short-time delayed short-circuit
release and for ground-fault protection.
If enabled for releases without ground-
fault protection, ZSI is only implemented
for the short-time delayed short-circuit
release.
