Function

EntelliGuard TU 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 frame equipped with a
suitable rating plug has a long-time trip value equal
to the ampere rating marked on the rating plug. For
example, a breaker frame with a 1600 A sensor and
an 800 A rating plug has an 800 A continuous current
(long-time) rating.

The available rating plugs for the AKR , Power Break,
WavePro and EntelliGuard families are listed in Table 1.
Not all sensors listed in Table 2 are available in all circuit
breakers.

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.

Installation

Before installing a rating plug into an EntelliGuard TU trip
unit, inspect the plug for damage, then follow these steps:

1. Verify that the rating plug catalog number matches
the desired continuous current rating and is suitable
for the circuit breaker’s sensor based on the
minimum and maximum sensor rating defined on
the rating plug’s catalog number.

2. Hold the rating plug between the thumb and
forefinger, then push it into the trip unit. Proper
engagement is verified by an audible and tactile click.

CAUTION: Do not attempt to push the rating plug into
the trip unit if there is resistance.

plug. Grasp the tabs of the rating plug with the tool,
as illustrated in Figure 2. Be careful to hold the tabs
and not the front cover, as the rating plug could be
damaged otherwise. Gently pry the rating plug out by
pulling away from the trip unit. A left–right wriggling
motion assists the removal. Insure that the tabs are held
securely until the Rating Plug is completely removed.

Removal

The rating plug is seated firmly in the trip unit. As
illustrated in Figure 1, there are tabs at the sides of
the rating plug for removal. A rating plug removal tool,
catalog number TRTOOL, also known as an integrated
circuit (DIP) extractor, is required to remove the rating
