If the UVT is for AC use, an external controller will be installed. The controller is fitted to the left
side of the breaker as standard. The controller may be installed separately if required (please specify
location). Separate installation is necessary when mechanical interlocks are fitted. UVT controllers
incorporating time delay units are also available (contact us for details). Refer to dimensions of
terminal blocks for the mounting positions of UVT controllers.

outside the door. It consists of
an operating mechanism that

unit
an operating handle that is
mounted on the door, and a shaft

required length.
The appearance and operation
of this handle match those of
the door mounted handle
for Tembreak 2 MCCBs
(details in Section 5).
SECTION 8
This means that a switchboard
containing a combination of
TemBreak and TemBreak 2
MCCBs from this catalogue can
be operated with external operating
handles which all look the same,
and work the same way.

Interpole Barriers
SECTION 8
Interpole barriers provide maximum insulation between phases at the terminals of the MCCB.
They can not be fitted at the same time as any of the terminal covers. Interpole barriers can
easily be fitted to either end of an MCCB.

MCCBs , including those fitted with door mounted handles and some motor operators can
be supplied with Castell locking systems. Contact us for details.

MECHANICAL INTERLOCKS
Rear Interlocks
Rear interlocks consist of a mechanism mounted at the back of each MCCB of an adjacently
mounted pair. The interlock inhibits the closure of one MCCB if the other is already in the
ON position. MCCBs cannot be mounted directly to a flat plate, but are installed on a frame
to ensure space for the interlock mechanism.
Two MCCBs or switch-disconnectors of the same frame size may be rear interlocked.
An operating handle or motor operator can be fitted to an MCCB with rear interlock.
Wire Interlock
Wire interlocks consist of two mechanisms connected by a cable. The mechanisms are mounted
on the back of two MCCBs located at a distance from each other which is limited by the length
and bend radius of the cable. The mechanisms inhibit the closure of one MCCB if the other is
already in the ON position. MCCBs cannot be mounted directly to a flat plate, but are installed
on a frame to ensure space for the interlock mechanism.
Any two of the TemBreak MCCBs or switch disconnectors featured in this catalogue may
be wire interlocked.
An operating handle or motor operator can be fitted to an MCCB with rear interlock.
TemTransfer Automatic Changeover Controller
SECTION 8
TemBreak MCCBs can be configured to provide automatic supply changeover. They are
compatible with the TemTransfer changeover controller. Refer to section 5 for details.
Front Mechanical Interlock
Front interlocks are manually operated toggle locking devices which can be installed between
two adjacent MCCBs. Depending on the position of the interlock, one or other of the MCCBs
is inhibited from being in the ON position.
Two MCCBs or switch-disconnectors of the same frame size may be front interlocked.
Operating handles and motor operators cannot be fitted to MCCBs with front mechanical
interlocks.

INSTALLATION
Connection of Busbars and Terminated Cables
This method is standard for 800A frame models. Solid conductors or cables terminated
with compression terminals can be used.
Connection of Large Conductors and Multiple Conductors
Terminal bars are terminal extensions which can be fitted to line or load side terminals
and are used to connect large conductors and multiple conductors. Optional for 800A
frame, standard for 1250A and 1600A frame models.
