OVERVOLTAGE CATEGORY

• Equipment of CAT

is equipment for connection to circuits

in which measures are taken to limit the transient
overvoltages to an appropriate low level.

Note:

Examples include protected electronic circuits.

• Equipment of CAT

is energy-consuming equipment to be

supplied from the fixed installation.

Note:

Examples include household, office, and laboratory
appliances.

• Equipment of CAT

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.

• Equipment of CAT

is for use at the origin of the installation.

Note:

Examples include electricity meters and primary over-
current protection equipment.
