2-6 OPTIM TRIP UNIT RATING PLUG
The rating plug value (I
n
) determines the maximum con-
tinuous current rating of the circuit breaker. All the pro-
tection function settings are based on multiples of the
plug rating. These settings are displayed as actual
ampere values for ease of use.
Notice: The primary current conductors (cable or bus)
must have ampacity ratings equal to the rat-
ing plug value per NEC Section 240-6(b).
OPTIM Trip Units use interchangeable rating plugs
(Figure
2-13 ). Rating plugs are designed for use with
one specific circuit breaker type. The circuit breaker type
is indicated on the rating plug. Rating plugs are suitable
for both 50 and 60Hz operation. A rating plug must be
selected to match the desired continuous current rating
of the circuit breaker as well as the installed sensor rat-
ing. The available rating plugs are shown in Table
2.1 .
