Professional Installation Requirements
- Installation and connection to mains electrical circuits should be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable local approval requirements.
Applications
- Three-phase domestic distribution boards
- Commercial switchboards and final distribution boards
- Light industrial control panels
- Protection of mixed resistive and inductive circuits
- Motor and equipment branch circuits where a C-curve MCB is appropriate
Standards & Compliance
- IEC/EN 60898-1 product standard stated by the manufacturer
- AS/NZS 60898.1:2024 is the applicable Australian/New Zealand standard for household and similar AC circuit-breakers; verify local approval and RCM requirements before installation
- AS/NZS 3000 applies to selection, installation and verification within Australian electrical installations
Environmental Benefits
- Energy-limiting Class 3 performance can reduce let-through energy and equipment damage during short-circuit events
- Long mechanical and electrical service life can reduce replacement frequency and associated waste
- Metal and thermoplastic components may be recoverable through appropriate electrical equipment recycling streams
