Internal Accessories
Internal accessories include Auxiliary and Alarm contacts, Shunt Trip and Undervoltage Trip (UVT) modules, which may be installed under the front cover of
the MCCB in various combinations to provide additional functionality and connection with external control circuits.
Auxiliary & Alarm Switches
Auxiliary Contact
An auxiliary contact can be installed to indicate whether an MCCB is Open (both OFF and
Tripped positions) or Closed (ON). Auxiliary contacts come in either general purpose, heavy
duty or micro-switch type, with some combinations pre-wired or with terminals. Each contact
type is provided as a single change-over switching arrangement (1x C/O), or normally-open
(1x N/O) for option in heavy-duty.
Alarm Contact
An alarm contact can be installed to indicate whether an MCCB is in the Tripped or Not
Tripped position (ON, OFF). Alarm contacts come in either general purpose, heavy duty or
micro-switch type, with some combinations pre-wired or with terminals. Each contact type is
provided as a single change-over switching arrangement (1x C/O), or normally-open (1x
N/O) for option in heavy-duty.

Precautions
Mounting Angles
TemBreak PRO MCCBs may be mounted at any angle without affecting performance.
Direction of Power Supply
Power supply may be fed in either direction with respect to the MCCB without affecting performance.
WARNING: To prevent electrical shock and damage to equipment, disconnect and isolate power source
upstream of the MCCB before installing or servicing the MCCB including its connected accessories.
Notice: To ensure correct performance, and integrity of equipment, the installation instructions and
recommendations provided herein shall be respected. Refer to the respective user manual and installation
instructions provided with the MCCB and associated accessories.

Clearances
Phase to Phase and Earth
Interruption of large currents during fault or normal switching operation produces ionised gases and arcing materials which expelled from the vents at the top
of the MCCB. These ionised gases are highly conductive, concentrated, and at an elevated temperature when it exits the MCCB via the arc vents. Care
must be taken to avoid an arcing fault from occurring due to the presence of concentrated ionised gases creating a conductive path between exposed
conductors. Incoming conductors must therefore be insulated the full length up to the terminal opening of the MCCB, ensuring bare conductors are not
exposed directly to concentrated ionised gases. This also applies to the attached busbars supplied as part of the MCCB.
Interpole barriers or terminal covers may be used to achieve creepage and clearance requirements. Conductors must not impede the flow of ionised gas
and allow it to clear and disperse safety. Interpole barriers are supplied as standard with Terasaki MCCBs for the line side only. 2 barriers with 3P MCCBs
and 3 with 4P MCCBs. In cases where two different MCCB types are installed one above the other, the insulation distance between the two models should
be as for the lower model.
WARNING: Exposed conductors including terminals at attached busbars must be insulated to avoid possible
short-circuit or earth faults due any foreign matter coming into contact with the conductors.

TemBreak PRO B_BE-UM-001-EN V1.1.0
Insulating Distance
When earth metal is installed within proximity of the breakers, the correct insulating distance must be maintained, (refer to Minimum Clearance).
This distance is necessary to allow the exhausted arc gases to disperse. This could include the mounting plate or side panel within a switchboard.
Minimum Clearance
Below illustrates the minimum clearance that must be maintained.
