ABB Power Plus Trip Unit Rating Plugs Instructions

Power+™ Trip Unit Rating Plugs
Power Breake I} Circuit Breakers
Function
Power+™ Trip Units are designed with UL-listed
interchangeable Rating Plugs. These Rating Plugs
change the per-unit (1X) continuous-current rating of
the breaker. A circuit 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 Power Break II insulated-case circuit breakers
is listed in Table 1. See DEH-049, Power+™ Trip Units
User’s Guide, for a complete listing of all Rating Plug
catalog numbers.
UL Label
The UL label is mounted on the side of the Rating
Plug and is not visible when the Rating Plug is
installed. The label lists the circuit breaker frames that
will accept that Rating Plug.
