Professional Installation Requirements
  • Installation, testing and connection to mains wiring must be carried out by a licensed electrician in accordance with AS/NZS 3000 and the applicable switchboard requirements. Confirm fault levels, cable sizing, discrimination and local approval requirements before installation.
Applications
  • Domestic distribution boards
  • Commercial electrical switchboards
  • Lighting and general-purpose final circuits where a D-curve characteristic is appropriate
  • Transformer and motor circuits with high starting current
  • Low-voltage AC power distribution systems
Standards & Compliance
  • AS/NZS 60898.1: applicable Australian and New Zealand standard for household and similar miniature circuit-breakers; confirm product marking and local certification before installation
  • AS/NZS 3000: installation and wiring requirements for Australian electrical installations
Environmental Benefits
  • Long mechanical and electrical service life can reduce replacement frequency and product waste
  • End-of-life separation supports recovery of metal and thermoplastic components
  • Modular construction allows replacement of the protective device without replacing the complete switchboard assembly
