7.0 RATING PLUG
The rating plug, as illustrated in Figure
16
, is used to
establish the continuous ampere rating of the related cir-
cuit breaker.
For adjustable rating plugs (Table
1-2
), the primary cur-
rent carrying conductors used with the breaker must be
sized to correspond with the maximum setting of the rat-
ing plug, in accordance with National Electrical Code
requirements.
The Long Delay protection function of the trip unit is set
at the rating plug value (I
n
).The Short Delay and
Instantaneous protection functions are set as a multiple
of I
n
. The Ground Fault protection function is indepen-
dent of I
n
.
Different rating plugs are available (Table
1-2
) to match
the desired current rating and type of circuit breaker into
which the trip unit is to be installed.
Complete catalog descriptions of all available rating
plugs are given in the applicable circuit breaker supple-
mentary instruction leaflets (see Section 8.0).
