Measurement categories

The MX809B ensures protection against electric shock
with double and reinforced insulation as well as defined
clearance and creepage distances. This insulation must
be designed both for continuously applied voltage (work­
ing voltage) and for possible, additional transient over­
voltages (transients).
Different influences can cause the supply network to be
superimposed with transients. EN 61010-2-030 divides
these zones into measurement categories, in accordance
with the level of these transients and the energy capacity
of the network segments:
