Extensive range of control units and communication

The Digitrip

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 ARMS

– greater safety for maintenance personnel

In the event of an arc fault the patented ARMS

(Arcflash Reduction Maintenance System)

trips faster than a short-circuit release. In conjunction with the NRX (IZMX) series, additional

components of the ARCON

arc fault protection system offer additional arc fault protection.

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 communica-

tion 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.
