Data sheet
1Description
The UT 6-TMC M circuit breaker is a single-position
overload circuit breaker with thermomagnetic tripping. It is a
space-saving circuit breaker with trip-free mechanism in the
event of overload and short circuits within the maximum
interrupting rating. The UT 6-TMC M is mounted on an
NS 35 DIN rail.
UT 6-TMC M thermomagnetic circuit breakers feature a
compact design, large labeling areas, and a double plug-in
bridge shaft.
The circuit breakers provide a high level of system
availability thanks to their reclosure function and clear status
display.
Eleven nominal current versions can be selected from 0.5 A
to 16 A. The large center labeling area enables clear
assignment of the relevant circuit breaker.
NOTE: The magnetic tripping ranges differ for alternating currents (AC) and direct currents (DC) (see page 3). The
magnetic operating currents for direct currents (DC) are approximately 1.6 times higher.
NOTE: When mounted in rows with simultaneous load, a mutual thermal effect occurs (see page 4).
Calibration is required for an ambient temperature of +23°C. A correction factor must be used to determine the
nominal current for a lower or higher ambient temperature (see page 5).
Make sure you always use the latest documentation.

3.2 Effect on thermal tripping of mounting in rows
The mutual thermal effect is tantamount to an increase in the
ambient temperature (see page 5). This depends on the
following:
– The nominal current
– The ambient temperature
– The number of devices
– The distance between devices
The nominal device current can be either overdimensioned
or limited. When the UT 6-TMC M is mounted in rows, the
correction factor is usually in the range of 1.25 or at
80% (reciprocal) in relation to the limiting nominal current.
These values apply in the event of continuous load and at an
ambient temperature of +23°C.
Since the thermal effect varies for each planned installation
when mounting in rows, the correction factors must be
defined individually and tested.
Calculation example for overdimensioning
5 circuit breakers with In = 10 A are to be mounted in rows.
The ambient temperature is +23°C.
