TECHNICAL DATA
1. Current and Time Adjustments
Overcurrent Low-set Current (l>) Adjustment
• This adjustment is for setting the minimum overcurrent
for tripping with time delay.
• The setting range is from 2A to 6A.
Overcurrent High-set Current (l>>) Adjustment
• This adjustment is for setting the instantaneous tripping
current due to an overcurrent.
• The setting range is from 1x to 10x of the overcurrent
low-set setting value.
l>> = a x l>,
a = 1 to 10
• This high-set feature can be disabled by setting the
tripping current to infinity (
'
)
Time Multiplier (TM) Adjustment
• The time multiplier is for setting the normal inverse time/
current characteristic (IDMT) as according to BS142.
• The setting range is from 0.05 to 1.0.
