6.4

Derating and temperature compensation

6.4.1

Derating of 3VA1 molded case circuit breakers

The temperature inside the molded case circuit breaker is influenced by the ambient

temperature and the current-dependent power loss generated inside the unit. To prevent

overloading of 3VA1 molded case circuit breakers under difficult thermal conditions, the

maximum rated continuous operational current must be limited as a function of the ambient

temperature.

Note
The values were calculated for molded case circuit breakers without accessories. They do

not apply to all installation situations of the molded case circuit breaker and may deviate

depending upon factors such as cables and busbars, packing density, ventilation, etc.
Please observe the applicable overriding guidelines (e.g. IEC 61439).

1)

For TM120M only (starter protection circuit breaker)

No derating up to the rated operational current I
