OVERVOLTAGE CATEGORIES
—
The information on overvoltage categories is
extracted from IEC 60664-1
Considered. P
Overvoltage category is a numeral defining a
transient overvoltage condition
Considered. P
Equipment of overvoltage category IV is for use at
the origin of the installation
N/A
Equipment of overvoltage category III is equipment
in fixed installations and for cases where the
reliability and the availability of the equipment is
subject to special requirements
N/A
Equipment of overvoltage category II is energy
consuming equipment to be supplied from the fixed
installation
Overvoltage category II. P
If such equipment is subjected to special
requirements with regard to
reliability and availability,
overvoltage category III applies
N/A
Equipment of overvoltage category I is equipment for
connection to circuits in which measures are taken to
limit transient overvoltages to an appropriate low
level
