Professional Installation Requirements
- Installation, testing and commissioning should be carried out by a licensed electrician in accordance with AS/NZS 3000 and applicable local electrical regulations. Confirm fault levels, cable sizing, discrimination and local approval requirements before installation.
Applications
- Residential switchboards and consumer units
- Commercial distribution boards
- Industrial control and power distribution panels
- Overload and short-circuit protection for final subcircuits
- Protection of resistive and inductive loads with moderate starting current
Standards & Compliance
- Applicable product standard: AS/NZS 60898.1:2024 for AC circuit-breakers used for household and similar installations
- Manufacturer documentation specifies IEC/EN 60898-1; verify Australian approval and RCM requirements before installation
- Installation should comply with AS/NZS 3000
Environmental Benefits
- Long mechanical and electrical service life can reduce replacement frequency and associated waste
- Compact modular construction uses less switchboard space and material than larger circuit-breaker formats
- End-of-life separation of metal and polymer components can support responsible electrical-equipment recycling
