here, the operate value for permissible current
unbalance of the phases is determined. The adjust-
able values are 50 % or "off". If the menu option
relay opt is enabled, on occurrence of the
parameterized unbalance, the output "optional sig-
nal" is set and the circuit-breaker is tripped after
elapse of the delay time set under relay tx.

adjustable values are in the range of (20 % to 150 %) x lr or "off".
Caution
The signal is only active after elapse of the delay time
set under menu option relay tx.
If the signal "lead time overload trip pending" is to be
used, this parameter must be set to off.

The rated current value may only be changed
when the release is removed (disconnected)
from the circuit-breaker. The entered value
must be identical to the value of the rated
current on the rating plate of the circuit breaker.
Incorrect entry will cause false or delayed
tripping. After I

relay g:
on - exceeding the operate value of the earth-fault protection
leads to trip
off - exceeding the operate value of the earth-fault protection
activates the earth-fault LED. Indication can only be reset
after the operate value has been undershot
This is possible only on overcurrent releases S and T.
relay temp:
on - exceeding the temperature limit in the release enclosure
activates the optional signal (the optional signal must be
enabled by the relay opt. menu option)
off - exceeding the temperature limit in the release enclosure
activates not signal
relay opt.
on - the optional signal is activated if at least one of the enabled
causes is present (Addition syml or relay temp)
off - optional signal is disabled
