  • Zero arcing-distance design for enclosed switchboard applications
Professional Installation Requirements
  • Installation, selection and coordination should be performed by a licensed electrical contractor in accordance with AS/NZS 3000, the manufacturer's instructions and applicable switchboard requirements. Confirm magnetic trip coordination, prospective fault current, conductor sizing and required RCM/EESS compliance before installation.
Applications
  • Motor feeder short-circuit protection
  • Industrial switchboards
  • Commercial electrical distribution boards
  • Mains and sub-main protection where magnetic-only protection is specified
  • Protection of electrical equipment and motor circuits
Standards & Compliance
  • AS/NZS IEC 60947.2: applicable low-voltage circuit-breaker standard
  • AS/NZS 3000: applicable requirements for installation within Australian and New Zealand electrical installations
  • Confirm product-specific RCM/EESS registration and marking before installation in Australia
Environmental Benefits
  • Durable moulded-case construction can support a long service life and reduce replacement waste
  • Copper, aluminium and steel components used in electrical switchgear are recyclable through appropriate metal-recycling streams
  • Magnetic-only protection avoids unnecessary thermal losses associated with some continuously energised electronic trip systems
