In most cases and notably for IP30 switchboards, convection takes place naturally
and does not require fans.
However, when the switchboard is installed in temperate environments or when the
degree of protection is high (IP55), ventilation accessories are indispensable. For
more in-depth information on selecting air-conditioning accessories and the thermal
management of switchboards, see page D-78.
