Professional Installation Requirements
  • Installation, selection and adjustment should be performed by a licensed electrician in accordance with AS/NZS 3000, the switchboard manufacturer's requirements and applicable electrical regulations. Magnetic-only protection does not provide thermal overload protection, so the complete motor protection arrangement must be correctly designed.
Applications
  • Switchboard mains protection
  • Three-phase industrial power distribution
  • Motor feeder short-circuit protection
  • Commercial and industrial electrical installations
  • Power distribution equipment requiring high fault-level protection
Standards & Compliance
  • IEC/EN 60947-2 manufacturer-declared product standard
  • AS/NZS IEC 60947.2 is the applicable Australian/New Zealand standard for low-voltage circuit breakers; verify local conformity and RCM requirements before installation
  • AS/NZS 3000 applies to selection and installation within Australian electrical installations
Environmental Benefits
  • Durable construction and long mechanical life can reduce replacement frequency and associated material waste
  • Metallic and thermoplastic components can be separated for recycling at end of service life where suitable recycling facilities are available
  • Efficient fault interruption helps limit equipment damage and reduce replacement of downstream switchboard components
