Applications
  • Residential switchboards and consumer units
  • Commercial electrical distribution boards
  • Industrial control and distribution panels
  • Overload and short-circuit protection for lighting and general-purpose circuits
  • Isolation and protection of two-pole AC circuits
Standards & Compliance
  • AS/NZS 60898.1: applicable Australian/New Zealand product standard for circuit-breakers for household and similar AC installations; verify model-specific approval and RCM requirements before installation
  • AS/NZS 3000: installation and wiring selection requirements for Australian electrical installations
  • CHINT NB1-63H product documentation lists IEC/EN 60898-1 compliance and an SAA certificate for the product family
Environmental Benefits
  • Thermal-magnetic protection can help limit equipment damage and reduce premature replacement waste
  • Long mechanical and electrical operating life supports extended service intervals
  • Modular construction allows the breaker to be replaced independently rather than replacing the complete switchboard assembly
  • Metal and thermoplastic components can be separated for appropriate end-of-life recycling where local facilities accept electrical equipment
