MicroVersaTrip Plus™ and MicroVersaTrip PM™ Trip Units
1-1 Read This First
The MicroVersaTrip Plus™ and MicroVersaTrip
PM™ Trip Units described in this publication are
used on Power Break® and Power Break® II
insulated-case circuit breakers, Type AKR low-voltage
power circuit breakers, R-Frame molded-case circuit
breakers, and low-voltage power circuit breaker
conversion kits.
Spectra RMS™ molded-case circuit breakers use
different versions of MicroVersaTrip Plus and
MicroVersaTrip PM Trip Units that are not
interchangeable with the units described here. Refer
to GEH-5934 for information on these Trip Units.
1-2 Product Structure
MicroVersaTrip Trip Units come in two different
sizes that are not interchangeable. The larger Trip
Unit (series RMS9C) is used on Power Break circuit
breakers, Type AKR circuit breakers, and conversion
kits. The smaller Trip Unit (series RMS9D) is used
only on Power Break II circuit breakers. Each of the
two sizes is available in both MicroVersaTrip Plus
and MicroVersaTrip PM configurations. The front
views of the MicroVersaTrip PM Trip Units are
shown in Figures 1 (RMS9C) and 2 (RMS9D).
Chapter 1. Introduction
Figure 1. Front view of MicroVersaTrip PM Trip Unit (series
RMS9C).
The RMS9C Trip Unit has a 36-pin rear connector,
while the RMS9D Trip Unit has a 50-pin rear connector, as shown in Figures 3 and 4. These connectors provide the Trip Units’ main connections to the
circuit breaker frame and to the equipment control
signals.
Both types of Trip Unit have recessed connectors in
the front panel to accept interchangeable current
rating plugs.
Both types of Trip Unit have a top-mounted 20-pin
connector that provides future access to the optional
Remote Display accessory. (
normally used with a Power Break II circuit breaker.)
This connector has a removable cover to protect it
when not in use.
Series RMS9D Trip Units also have a 6-position DIP
switch, not present on series RMS9C Trip Units, that
is used to configure the Power Break II integrated
accessories. This switch is located on the rear of the
unit.
Note:
this accessory is not

1-3 Trip Unit Functions
MicroVersaTrip Plus and MicroVersaTrip PM Trip
Units have specific standard and optional functions.
All Trip Units share a series of interchangeable
rating plugs. The standard functions for both types
of Trip Unit are as follows:
• Protection
– Long-time protection
– Instantaneous protection
• Status
– Trip target (trip type)
– Trip information (magnitude and phase)
– Trip operations counters
• Metering display
– Phase current (selectable among phases)
The optional functions available on both types of
Trip Unit are as follows:
• High-range (fixed) instantaneous overcurrent
protection
• Short-time protection, with or without I
• Ground-fault protection, with or without I
• Defeatable ground fault, with or without I
• Zone-selective interlock, with ground fault only
or with both ground fault and short time
protection
Additional optional functions available only with
MicroVersaTrip PM Trip Units are as follows:
• Available configurations
– Communication and metering
– Communication and protective relaying
– Communication, metering, and protective
relaying
• Remote communication with POWER
LEADER™ communications network
(commnet)
• Metering functions
– Voltage (V)
– Energy (kWh/MWh/GWh)

1-4 Trip Unit Catalog Numbers
A simple catalog-numbering system defines all of the
standard and optional Trip Unit functions for each
of the two series of Trip Units. Catalog number keys
are found in Appendix 1 for AKR breakers,
Appendix 2 for RMS9C Trip Units in Power Break®
breakers, and in Appendix 3 for RMS9D Trip Units
in Power Break® II breakers. A208LIPMR is an
example of a valid catalog number.
The first character of each catalog number defines
the type of breaker for which it is configured, as
listed in Table 1.

installed protective functions, as in Table 4. These
suffixes are valid for both MicroVersaTrip Plus and
MicroVersaTrip PM style Trip Units. They are

MicroVersaTrip Plus™ and MicroVersaTrip PM™ Trip Units
Chapter 1. Introduction
1-6 Equipment Interfaces
MicroVersaTrip Plus Trip Units
MicroVersaTrip Plus Trip Units do not usually
require connections within the equipment, since all
wiring is contained within the circuit breaker. The
only two connections are for optional zone-selective
interlock (Z1 and Z2), made by secondary disconnect, and the neutral sensor, which uses a special
dedicated disconnect.
Zone-selective interlocking coordinates breakers, so
that the downstream breaker is allowed the first
opportunity to clear a disturbance. The two types of
available zone-selective interlocking are Z1, which
reacts only to ground faults, and Z2, which reacts to
both ground faults and short-time overcurrent pickups.
Neutral Current Sensors
CCCCAAAAUUUUTTTTIIIIOOOONNNN::
single-phase, three-wire and three-phase, four-wire
systems. When the Trip Unit is connected to a threephase, three-wire system, the neutral sensor
terminals of the breaker are left open. Do not short
any neutral current sensor terminals in a threephase, three-wire system, as this could result in damage to, or malfunction of, the electrical system.
::
Neutral current sensors are required for
RMS9C-type MicroVersaTrip PM Trip Units require
a connection to an auxiliary switch within the
breaker that senses the breaker position. This
connection is not required for RMS9D-type
MicroVersaTrip PM Trip Units used on Power
Break® II breakers.
POWER LEADER™ Communication Network
The POWER LEADER Communication Network
(commnet) transmits data and instructions between
the Trip Unit and an external intelligent device. The
external device may be the POWER LEADER system,
the Epic system, or a POWER LEADER Monitor.
Devices on commnet may be up to 1000 feet apart
without signal repeaters, subject to certain constraints. A maximum of 30 devices can be connected
without a signal repeater. Refer to GEH-5943 for
installation and operation of the POWER LEADER
system.
Commnet connections are made directly to wiring
terminations on breaker frames. All commnet connections to the Trip Units are made through the 36pin or 50-pin plug on the Trip Unit, which mates
with a receptacle on the breaker frame. These additional connections are made to the equipment
through the secondary disconnects of the breaker.
Voltage Inputs
AAAATTTTTTTTEEEENNNNTTTTIIIIOOOONNNN::
neutre est nécessaire pour les réseaux 3 phases +
neutre. Si le neutre n’est pas distribué, les bornes de
neutre du déclencheur doivent être laissées ouvertes.
Ne pas les court-circuiter (ceci peut endommager le
déclencheur et entrainer un mauvais
fonctionnement du système électrique.

MicroVersaTrip PM Trip Units
In addition to the inputs received by MicroVersaTrip
Plus Trip Units, MicroVersaTrip PM Trip Units also
receive inputs from external voltage conditioners, a
+24 Vdc control power supply, and communication
connections. External +24 Vdc control power is
required for operation.
Voltage inputs are sensed by conventional instrument potential transformers(PTs). PTs have 120 Vac
secondaries and must always be used in groups of
three; no open-delta connections are permitted. PT
primaries are connected either line-to-line or line-toneutral, as required.
PTs may be used for other monitoring functions,
subject to reasonable burden limitations. Note that
PTs must be connected in a specific sequence to
ensure proper phase relations and power-flow sensing.
Each PT output feeds an individual voltage conditioner that scales the nominal voltage to approximately 1.76 Vac for use by the Trip Unit.
