The SETUP procedures should only be repeated if the trip unit or
the protecƟon characterisƟcs are changed, requiring diīerent
set points and Ɵmedelays.
All trip units provide long Ɵme over current protecƟon, long
Ɵme delay, and some form of short circuit current protecƟon
when installed in circuit breakers. All other funcƟons are
opƟonal.
If a speciĮc set of trip unit funcƟons, such as relaying or short
Ɵme over-current protecƟon is not installed that funcƟon will
