Breaker fixing bolts
The breaker fixing bolts hold the breaker
body securely to the draw-out cradle in
position. Use them if the ACB is subject
to strong vibration.
Position padlock lever
Using the position padlock lever pre-
vents the breaker body from inadvert-
ently being drawn out. The position pad-
lock lever in the pulled-out position locks
the breaker body in the CONNECTED,
TEST, or ISOLATED position. Up to
three padlocks (with ø6 hasp) can be
installed.
Mal-insertion prevention device
Interchangeability exists within the
TemPower2 series of ACBs. Because
of this feature, there is a possibility for
an ACB of a different specification be-
ing placed into the draw-out cradle.
Using the mal-insertion prevention de-
vice eliminates such a possibility.
This device is capable of distinguishing

Door interlock

The door interlock prevents the switchboard door from being opened unless the breaker body is in the ISOLATED position.
When the draw-out handle is removed while the ACB is in the ISOLATED position, the interlock is released and the switchboard
door can be opened.
The breaker body cannot be inserted unless the switchboard door is closed.
Contact Terasaki for details.
Note 1: When the door interlock is installed, the standard draw-out handle cannot be stored in the switchboard. A storage draw-
out handle is available as an option. The storage draw-out handle can be housed flush with the front surface of the
ACB. (The storage handle will incur extra cost).
Note 2: Contact TERASAKI for the details for fitting Door interlock with IP55 cover.
