Function
ProTrip™ Trip Units are designed with interchangeable
Rating Plugs. These Rating Plugs change the per-unit
(1 ) continuous-current rating of the breaker. A circuit
X
breaker equipped with a suitable Trip Unit and Rating
Plug has a long-time trip current equal to the ampere
rating marked on the Rating Plug times the LT setting on
the Trip Unit.
For example, a breaker frame with a 1600 A sensor, an 800
A Rating Plug, and a long-time pickup switch setting of 1.0
has an 800 A continuous-current (long-time) rating.
Several Rating Plugs are available for each sensor rating
and each Rating Plug is keyed for a particular sensor
rating.
The catalog number structure for the available Rating
Plugs for ProTrip conversion kits is listed in Table 1. See
DEH–40034, ProTrip™ Trip Units User's Guide, for a
complete listing of all Rating Plug catalog numbers.
