Manually operated cable
• Standard length is 2m and 2.6m. Custom-made,
1.2m, 5m should be discussed separately.
• Turn the the hand wheel to the right for 50 times and
manual input is completed, while turn it to the same
direction for 8 times, the opening operation is completed.

inrush current suppression
• When ASS operates normally (if current is 10%
100% current correction tab), blocks opening
operation and it is put into operation again, this
function suppresses malfunction of which ASS
mistakes the current as a fault current due to inrush
current of backup protective equipment of ASS.
Overload protection
• It is operate according to the inverse characteristic
curve in less than an overcurrent lock of 800A.
Stored energy Trip
• Although blocking is operated according to the T-C
curve due to overload or ASS is not blocked since the
overload is removed, if backup protective equipment
is operated so that no voltage is generated, the ASS
will be instantaneously released and disconnects line
of back of the ASS.
Overcurrent lock
• While ASS protects the switching when failure of rated
breaking current (900A) occurs, if the current is greater
than the lock current (800A ± 10%), the switch will
be LOCK status. The fault current will be removed
by the backup protective equipment and ASS will be
blocked in the non-voltage status.

Overload protection • It is operate according to the inverse characteristic curve in less than an overcurrent lock of 800A.

Overcurrent lock • While ASS protects the switching when failure of rated breaking current (900A) occurs, if the current is greater than the lock current (800A ± 10%), the switch will be LOCK status. The fault current will be removed by the backup protective equipment and ASS will be blocked in the non-voltage status. ➊ ➋ ➏ ➌ ➎ ➍ ➑ ➒ ➓➐ [Structure] [Feature] Control box Auto Section Switch ➊ Arc extinguish part ➋ Primary terminal ➌ Main movable part ➍ Arc contact ➎ Fuse holder ➏ Fuse ➐ Secondary terminal ➑ Insulation support ➒ Arrester LA ➓ C.T Operator ASS structure
