UT 6-TMC M...

3.2

Effect on thermal tripping of mounting in rows

Calculation example for overdimensioning

5 circuit breakers with I_n= 10 A are to be mounted in rows.

The ambient temperature is +23°C.

Nominal current when not mounted I_n= 10 A

in rows

NOTE: When mounted in rows with simultaneous

load, a mutual thermal effect occurs.

The mutual thermal effect is tantamount to an increase in the

ambient temperature (see page 5). This depends on the

following:

Typical correction factor

d_f= 1.25

Theoretical nominal current when

mounting in rows

I_{n row}= 10 A X 1.25

= 12.5 A

–

The nominal current

The ambient temperature

The number of devices

The distance between devices

3.3

Internal resistance of the UT 6-TMC M

Nominal current

0.5 A

Resistance

4.37 Ω

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.
