Description
Power coefficient 4 in ablation
calculation formula
Ablation threshold for warning state
Minimum current limit for ablation
calculation
Beyond this current limit, ablation value
of setting AblatCalShEst will be applied
Ablation for current exceeding higher
threshold
Number of error operations to trigger
warning operation alarm
Highest allowed correction value for
arcing time
Description
Coarse threshold for detecting
appearance of selected feedback signal
Fine threshold for precise detection of
start of selected feedback signal
Coarse threshold for detecting
disappearance of selected feedback
signal
Fine threshold for precise detection of
interruption of selected feedback signal
Scaling factor for UBase in load voltage
signal evaluation
Nominal circuit breaker RDDS for phase
LX
Expected gap voltage peak across
breaker contacts, prior to current
inception
Reference level for magnetic inrush
current peak evaluation in percent of
maximum RMS value
