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 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).
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 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).

SMART Auxiliary AX / AL Status Indicator
The SMART auxiliary is dedicated to TemBreak
PRO SMART MCCB range. It allows the SMART OCR to
log and count the number of opening / closing cycles, counting the number of electromechanical fault trips
and indicate the actual mechanical OPEN CLOSED TRIP status of the breaker’s main contacts. The
auxiliar y mounts inside the MCCB and is connected to the MCCBs OCR via the “ACP” connector socket
inside the MCCB, which is under the MCCBs accessory cover. It takes the position of 1 Aux and 1 Alarm on
the left-hand side of the MCCB.
The SMART contact blocks are available in three versions:
Part Number Description
TPSS00MXLSW Auxiliary contact SMART AX / AL, standard type use for applications 125 – 250 Vac
TPSS00MXLRW Auxiliary contact SMART AX / AL, micro-current type use for applications 125 Vac / 24 - 30 Vdc (e.g. PLC applications)
TPSS00NA AX / AL SMART MCCB Cycle Counter
Notice : The TPSS00MXLSW and TPSS00MXLRW types include voltage free switching contacts AX and AL.
These contacts are provided with pre-wired wired contacts.
Notice : It is recommended to use 24 Vdc backup supply to the MCCB to ensure the SMART AUX continues to
operate in the event of upstream power failure.
