Applications
  • Domestic distribution boards
  • Commercial electrical switchboards
  • Control panels and modular distribution assemblies
  • Circuits supplying transformers and other high-inrush loads
  • Low-voltage AC overload and short-circuit protection
Standards & Compliance
  • The product documentation specifies IEC/EN 60898-1, corresponding to the AS/NZS 60898.1 circuit-breaker standard family; confirm Australian approval and RCM requirements before installation.
  • Installation in Australia must comply with AS/NZS 3000 Wiring Rules.
Environmental Benefits
  • Metal components such as copper and steel can be recovered through appropriate electrical equipment recycling streams.
  • Thermal-magnetic protection helps prevent equipment damage and premature replacement caused by overloads and short circuits.
  • Long mechanical and electrical operating life can reduce replacement frequency and associated material waste.
