Ventilation
The ABB MNS R switchgear have
been studied to create separated air
flows for all the internal compartments
in order to guarantee an efficient natu-
ral ventilation to all the installed com-
ponents. Ventilation grides for natural
cooling are placed on the front and
rear side of the the panel on both, top
and bottom positions, and on the roof
as well.
