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 groundfault
protection, ZSI is only implemented for the short-
time delayed short-circuit release.
