NRX circuit-breakers from Eaton: small, flexible and efficient

21 July 2013

Eaton's new NRX series circuit-breakers offers different rated currents for a wide range of applications, from 630A to 4,000A and breaking capacities from 42kA to 105kA. 

Included in the new series is the IZMX16 which is believed to be the smallest air circuit-breaker in the world. The novel space-saving design allows side-by-side mounting of two removable circuit-breakers in a 600mm wide panel. Remote switching capability is also included.

The IZMX40 (4,000A capacity) takes up no more space than a 3,200A circuit-breaker and does not require any additional cabling in the terminal area.

A range of accessories is available to extend the functionality of the circuit-breaker with regard to signalling, automation and communication.

Eaton offers three related software tools: Configurator Circuit Breaker, which enables simple selection and configuration of circuit-breakers and switch-disconnectors with accessories from a database of several thousand items; CurveSelect, a tool enabling the tripping characteristics of several protective devices over the same time and current ranges to be congfigured, and BreakerVisu - data acquisition for circuit-breaker currents, switching states and load warnings.
