12 IZMX circuit-breakers, INX switch-disconnectors IZMX circuit-breakers, INX switch-disconnectors Space-saving circuit-breakers with useful accessories IZMX circuit-breakers, INX switch-disconnectors Eaton Introduces Series NRX! The new NRX series from Eaton is a new series of air circuit-breakers with an extensive range of accessories.
IZMX circuit-breakers, INX switch-disconnectors 13 IZMX circuit-breakers, INX switch-disconnectors Communication capability The communication-capability of Series NRX circuit-breakers open up new possibilities in power distribution. The trip unit provides all important operation information and passes this on via one of the various communication adapter modules. This increases system transparency and shortens the response times to states such as overcurrent, phase asymmetry and overvoltage.
14 IZMX circuit-breakers, INX switch-disconnectors IZMX circuit-breakers, INX switch-disconnectors Communication Options for Series NRX Modbus configuration For the Series NRX range, PROFIBUS-DP or Modbus RTU communication protocols are supported by optional fieldbus connection accessories. Communication adapter modules are compact units for direct mounting in the auxiliary terminal strip. When retrofitting, four auxiliary terminals are replaced with one communication module.
