but the breaker is still not closed. This is done by setting parameter AutoCont =Enabled
and tAutoContWait to the required delay for the function to proceed without a new start.
11.3.2.19 Thermal overload protection holding the auto-reclosing function back
If the input THOLHOLD (thermal overload protection holding reclosing back) is
activated, it will keep the reclosing function on a hold until it is reset. There may thus be
a considerable delay between start of Auto-Reclosing and reclosing command to the
circuit-breaker. An external logic limiting the time and sending an inhibit to the INHIBIT
input can be used. The input can also be used to set the Auto- Reclosing on hold for a
longer or shorter period.
