Electromagnetic compatibility
The user of specific devices in an industrial environment can result in electromagnetic
interference in the electrical installation. The circuit breaker has been developed and tested
for electromagnetic compatibility in compliance with IEC 60947-2, Annexes J and F.
Installation altitudes
An installation altitude above 2000 m can result in higher temperatures on the switching
devices. The lower density of air can significantly reduce heat dissipation. The arcing
behavior and the conductivity of the density-dependent ionized gas mixture are also less
favorable at greater altitudes. This makes it necessary to decrease rated operational voltage
and the rated uninterrupted current.
