Heat, radiation, noise and gases

Heat
In general, it can be said that the heat generated in full-
load service will lead to a maximum temperature rise of the
outer surface not exceeding the body temperature.
Radiation
Radiation is well below the safety standard level.
Noise
In general it can be stated that the switchgear does not
generate any noise under operating conditions apart from
switching operations. The noise during switching
operations is less than 70 dB(A), such that noise protection
measures are not required.
Gases
Before service, in service and after service no gases will be
released (except when an electric arc develops).
