Professional Installation Requirements
- Installation, testing and commissioning must be performed by a licensed electrician in accordance with applicable Australian electrical requirements, including AS/NZS 3000. Confirm that the selected breaker is approved for the intended installation and system fault level before use.
Applications
- Domestic distribution boards
- Commercial switchboards
- Lighting and general-purpose circuits
- Residential and light industrial electrical installations
- Overload and short-circuit protection in AC distribution systems
Standards & Compliance
- IEC/EN 60898-1 manufacturer-declared product standard
- AS/NZS 60898.1:2024 is the applicable Australian/New Zealand standard for circuit-breakers for overcurrent protection in household and similar AC installations; local approval should be confirmed before installation
- Installation must comply with AS/NZS 3000 Wiring Rules
Environmental Benefits
- Long mechanical and electrical service life can reduce replacement frequency and material waste
- Metal and thermoplastic components can be separated for recycling at end of service life where suitable recycling facilities are available
- Provides passive electrical protection during normal operation without continuous energy consumption
- Replaceable modular construction can support maintenance of switchboards without replacing the complete assembly
