Equipment of OVERVOLTAGE CATEGORY I 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 OVERVOLTAGE CATEGORY II is energy-consuming equipment to be 
supplied from the fixed installation. 
Note – Examples include household, office, and laboratory appliances. 

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. 

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
