 NRX Low Voltage Power Breakers
 


NRX Low Voltage Power Breakers


Product Catalog - Circuit Protection 2MB


Features:

 

  • Rogowski coil does not saturate like iron core sensors, and one sensor accommodates 200-1600A range. Never change a sensor, and NO CTs are required

  • Tension clamp secondary terminals--10A continuous rating at 600V meets UL/CSA/RoHS and UL-94 V0. Mounted directly to fixed breaker or drawout cassette they reduce wiring and provide clean, organized wiring schemes

  • Breaker mounted communication modules for INCOM™, Modbus® and PROFIBUS® mount directly to the cassette, reducing the space and room required for communication capability

  • With the patent pending simple design of the fold-up cassette, all items in a cassette are replaceable without removing the cassette from the cell

  • Plug-and-play accessories--no special tools needed. Accessories come with plug and wires ready to install
