403006 0 0x0001 Thermal memory
(overload protection)
R/W Encoded 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:
0: switched off
1: switched on

403007 0 0x0001 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.
