Description
Overview
For the compact circuit-breakers NZM
Eaton supplies the following energy
measurement and communication
components:
• NZM-XPC-Soft: Diagnostics
software
• CurveSelect: Software for viewing
characteristic curves
• NZM-XMC-S0: Energy measuring
module
• NZM-XMC-MB: Measuring and
communication module
• NZM-XSWD-704: Communication
interface for SmartWire-Darwin
with S0 input for energy data
• NZM-XDMI612: Data management
interface with field bus connection
for PROFIBUS-DP and bus
diagnostics software
XPC-Soft
Circuit-breakers NZM with electronic
trip block provide all required
diagnostics data directly to the USB or
COM interface of a connected PC
through a built-in interface.
On overload or short-circuit, the NZM
instantly switches off the system and,
if a PC is connected, documents the
events complete with date and time.
With the software XPC-Soft, users can
view the history and analyze possible
causes. The software can also output
power consumption trend graphs as
MS Excel table.
CurveSelect
The free characteristic curve program
Moeller CurveSelect allows a settings-
specific representation of the tripping
characteristics of several protective
devices with the same time and
current scales.
This clearly simplifies an assessment
of the interaction of Eaton’s circuit-
breakers NZM and IZM, motor-
protective circuit-breakers PKZ,
overload relays ZB, miniature circuit-
breakers, and LV h.b.c. fuses.

Measuring and communication
module
For measuring and optimizing energy
consumption, Eaton provides module
NZM-XMC. This compact device with
built-in current converter determines
the power and energy values per
phase from the measured voltage and
current. The module can operate the
circuit-breaker through a remote
operator. The data is made available
on the MODBUS RTU.
With the XMC applications up to 500 A
can be operated; the readings have a
high accuracy of 0.5 %. Cables, strip or
bar can be used. The conductors pass
through a tunnel in the device and do
not have to be severed. An optional
external door display provides real-
time local indication of the measured
values.

Communication interface for
SmartWire-Darwin
For remote diagnostics of the circuit-
breaker, communication module
NZM-XSWD-704 is used. With this
module, the switch settings, trip
causes, and actual currents can be
transmitted to a field bus through
SmartWire-Darwin. The circuit-
breaker can therefore also be
operated through SmartWire-Darwin,
like the electronic motor protection
PKE and the typical devices such as
RMQ and DIL.
As a special feature, the XSWD
features a built-in power meter, which
can be supplied from an external
energy measurement module XMC-S0.
This provides everything that is
necessary for optimizing energy
usage.
With the data from the XSWD-704 all
relevant information about energy
supply or the respective outgoer on
the desired field bus are available. This
allows visualization and logging of the
machines or system components.
For visualization, the free software
BreakerVisu can, for example, be
used, available for download from

Data Management with PROFI-
BUS-DP interface
An alternative to the XSWD-704 is
provided by data management
interface NZM-XDMI612 with a field
bus connection for PROFIBUS-DP.
The advantages of this solution are:
• For motor starter applications a
ZMR function is available that does
not trip the circuit-breaker in the
event of an overload but that
deactivates the contactor through
the DMI.
• The built-in display provides a local
indication of all parameters of the
circuit-breaker.
• The DMI can change the circuit-
breakers’ tripping parameters.
(remote parameterization)
• The DMI’s six inputs and six outputs
can be used for remote control and
for any user functions.
• Through the outputs a “Tripped”
signal can be issued locally.
• A central diagnosis across the
entire bus to the FDT standard can
be implemented through the DMI
with the DPV1 module. For this
purpose, software NZM-XPC-DTM
and, in some cases,
FDT-FAVIGATOR are required.
