2.2. Per IEC1010 Overvoltage Installation Category
Overvoltage Category I
Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to
ciruits in wchich measures are taken to limit the transient overvoltages to an
appropriate low level.
Note:
Examples include protected electronic circuits.
Overvoltage Category II
Equipment of OVERVOLTAGE CATEGORY II is energy-consuming equipment
to be supplied from the fixed installation.
Note:
Examples include household, office, and laboratory appliances.
Overvoltage Category III
Equipment of OVERVOLTAGE CATEGORY III is equipment in fixed
installations.
Note:
Examples include switches in the fixed installation and some
equipment for industrial use with permanent connection to the fixed
installation.
Overvoltage Category IV
Equipment of
Overvoltage Category IV
is for use at the origin of the
installation.
Note:
Examples include electricity meters and primary over-current
protection equipment.
