CAT I: CAT I circuits are circuits protected by low level transient over-voltage
limiters
Example: protected electronic circuits
CAT II: CAT II circuits are household or similar appliance power circuits, which
may carry medium-level transient over-voltage.
Example: household appliance and portable tool power supplies
CAT III: CAT III circuits are high-power appliance power circuits, which may
carry high-level transient over-voltage.
Example: industrial machinery or instrument power supplies
CAT IV: CAT IV circuits are circuits which can carry very substantial transient
over-voltage.
Example: power feeders
