  • Designed for circuit, equipment and motor protection
Professional Installation Requirements
  • Installation, testing and commissioning must be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable local electrical requirements. Magnetic-only protection does not provide overload protection, so coordinated motor overload protection may be required.
Applications
  • Motor feeder short-circuit protection
  • Motor control centres and industrial control panels
  • Commercial and industrial switchboards
  • Main or sub-main circuit protection where magnetic-only tripping is specified
  • Electrical equipment and distribution circuits requiring high fault interruption capacity
Standards & Compliance
  • AS/NZS 60947.2 for low-voltage circuit-breakers
  • AS/NZS 3000 for installation within Australian low-voltage electrical installations
Environmental Benefits
  • Moulded-case construction includes recyclable copper and ferrous metal components
  • Long mechanical and electrical service life can reduce replacement frequency and product waste
  • CHINT publishes RoHS documentation for the NM8N product family, supporting restricted-substance compliance
  • Provides reliable fault protection that can help reduce damage to downstream electrical equipment
