GE MicroVersaTrip Plus User manual

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:
11
11 .... Verify that the Rating Plug catalog number
matches the desired continuous current rating (X)
and the sensor rating (S) on the breaker frame.
22
22 .... Hold the Rating Plug between the thumb and
forefinger, then push it into the Trip Unit. Proper
engagement is verified by a click.

CCAA AAUU UUTT TTII IIOO OONN NN::::
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.
NN
NNOO OOTT TTEE EE::::
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.
