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.
