Function

MicroVersaTrip Plus™ and MicroVersaTrip PM™ 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.

Several Rating Plugs are available for each sensor rating

and each Rating Plug is keyed for a particular sensor

rating.

The available Rating Plugs for the AKR and Power

Break® families are listed in Table 1.

Front Label

The front label, shown in Figure 1, is visible when the

Rating Plug is installed. The items listed are:

Sensor Rating (S) The ampere rating of the

corresponding breaker frame.

Rating Plug Amps (X) The Rating Plug continuous

current in amperes.

Test The test-jack receptacle is used

with Test Kit catalog number

TVRMS2 for overcurrent and

ground-fault functional testing.

Catalog Number Follows the format TRppBqqqq,

where pp refers to the sensor

rating (S) and qqqq refers to

the plug rating (X).

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 a MicroVersaTrip

Plus or PM Trip Unit, inspect the plug for damage, then

follow these steps:

Verify that the Rating Plug catalog number

matches the desired continuous current rating (X)

and the sensor rating (S) on the breaker frame.

Hold the Rating Plug between the thumb and

forefinger, then push it into the Trip Unit. Proper

engagement is verified by a click.

Do not attempt to push the Rating Plug

into the Trip Unit if there is resistance. This may

indicate the wrong Rating Plug for the sensor rating. Stop

immediately and verify that the breaker sensor rating (S)

and the Rating Plug nameplate “S=” value are the same.

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

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.

Protection to the breaker is maintained at only

25% of the sensor rating when the Rating Plug is

removed. If the breaker is carrying more than 25% of the

sensor load rating, the breaker will trip after the time-

delay setting.
