Magnetic-only protection must be coordinated with suitable overload protection where required.
Applications
  • Three-phase motor feeder short-circuit protection
  • Industrial control panels and motor control centres
  • Commercial and industrial switchboards
  • Low-voltage distribution systems requiring high fault-level protection
  • Switchboard incomer or feeder applications where the magnetic-only trip characteristics are suitable
Standards & Compliance
  • Applicable product standard: AS/NZS 60947.2 for low-voltage circuit-breakers
  • Electrical installation and switchboard application should comply with AS/NZS 3000 and relevant switchboard requirements
  • Australian sale and installation should be supported by applicable EESS and RCM compliance documentation
Environmental Benefits
  • RoHS documentation is available for the NM8N series, supporting restriction of hazardous substances
  • Durable moulded-case construction can support extended service life and reduce replacement waste
