Position switches
The position switch operates to give an indication of the breaker position: CONNECTED, TEST, ISOLATED, and INSERT.
There are two contact arrangements: 2c and 4c.
Connections to the switches are made via screw type terminals.
The following table lists the available types of the switches.
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.

Accessories for Draw-out Type
Main circuit safety shutters
The main circuit safety shutters auto-
matically conceal the main circuit con-
tacts on the draw-out cradle when the
ACB is drawn out.
• The top and bottom shutters operate
independently and can be separately
padlocked in the closed position.
• Up to three padlocks (with ø6 hasp)
can be installed on each side using
padlocking unit. (Padlock not supplied)
• In the closed position, the shutters are
locked to the extent that they cannot
be easily unlocked by hand. They can
be unlocked and held open if required
for the purpose of inspection or main-
tenance.
Control circuit safety shutter
The control circuit safety shutter covers
the control circuit contacts, ensuring
safety.
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.
Test jumper
The test jumper is a plug-in type, and
allows ON-OFF tests on all the
TemPower2
series ACBs with the
breaker body drawn out from the draw-
out cradle.
The standard jumper cable is 5 m long.
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.
Lifter
A special lifter is available to allow easy
and safe transportation or installation of
the ACB. A drop prevention mechanism
is standard.

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
nine different breaker bodies.
Please specify the Code 1A, 1B, 1C, 2A,
2B, 2C, 3A, 3B, 3C for each ACB.
