IZMX circuit-breakers,
INX switch-disconnectors,
from the NRX series up to 4000 A
Eaton's NRX series is a new line of circuit-breakers up to 4000 A. Engineering and
mounting requirements are reduced thanks to only two compact sizes, the modular
design and standard accessories. The highlight of the NRX series: The Digitrip 1150 P
trip electronics. It covers all possible applications. And in conjunction with a communication module ensures that operation can be monitored from all round the globe. The
innovative IZMX16 enables two circuit-breakers with a width of only 600 mm to be
mounted in a switch cabinet.
NRX Series
Rated operational current from 630 to 4000 A, switching capacity 440 V AC, Icu = Ics from 42 to
105 kA, 3 or 4 pole, fixed mounted or withdrawable, electronic releases for system protection,
selective, universal protection, professional protection.
Extensive mounting accessories for fixed mounting and withdrawable units
Motor operator IZMX…M… +++ Shunt release IZMX…ST… +++ Closing release IZMX…-SR…
+++ Undervoltage release IZMX…-UV… +++ Auxiliary contact ON-OFF IZMX…-AS… +++
Latch check switch IZMX…LCS… +++ Overload trip switch IZMX…-OTS +++ Mechanical
interlocks.
Extensive range of control units and communication
The DigitripTM control unit offers the most extensive range of functions in its class. It covers all
requirements: from simple system protection to professional protection with additional
parameter, protection, measuring, analysis, diagnostics and event memory functions that can
be shown on an LCD color display or transferred remotely via a communication module,
displayed on a web page or sent worldwide by email. Unique in this range: the LCD color
display. Digitrip can be integrated in different data networks together with Eaton’s plug & play
communication modules: ­MODBUS, PROFIBUS or Ethernet. Circuit-breakers can then be
monitored directly via the Internet.
Worldwide novelty ARMSTM – greater safety for maintenance personnel
In the event of an arc fault the patented ARMSTM (Arcflash Reduction Maintenance System)
trips faster than a short-circuit release. In conjunction with the NRX (IZMX) series, additional
components of the ARCONTM arc fault protection system offer additional arc fault protection.
