Professional Installation Requirements
- Installation, testing and commissioning must be performed by a licensed electrician in accordance with AS/NZS 3000 and applicable local electrical regulations. Confirm fault level, cable size, discrimination and suitability for the specific switchboard before installation.
Applications
- Residential switchboards
- Commercial distribution boards
- Light industrial control and distribution panels
- Protection of lighting, socket-outlet and general-purpose final circuits
- Overload and short-circuit protection for AC electrical installations
Standards & Compliance
- Manufacturer-declared IEC/EN 60898-1 performance; the applicable Australian/New Zealand product standard is AS/NZS 60898.1:2024
- Installation and selection should comply with AS/NZS 3000
Environmental Benefits
- Long mechanical and electrical service life can reduce replacement frequency and associated waste
- Metal components can be recovered for recycling at end of service life
- DIN rail modular construction supports replacement of the individual protective device rather than the complete switchboard assembly
