Professional Installation Requirements
- Installation and connection to mains electrical circuits must be carried out by a licensed electrician in accordance with AS/NZS 3000 and applicable local requirements. Confirm the prospective fault current, conductor sizing, discrimination and required RCM or SAA approval marking before installation.
Applications
- Residential switchboards
- Commercial electrical distribution boards
- Industrial control and distribution panels
- Protection of circuits supplying motors, transformers and other high-inrush loads
- DIN rail assemblies requiring two-pole overcurrent protection
Standards & Compliance
- AS/NZS 60898.1:2004 for miniature overcurrent circuit-breakers for household and similar installations
- Australian installation applications must also comply with AS/NZS 3000 Wiring Rules and applicable electrical equipment registration requirements
Environmental Benefits
- Long mechanical and electrical service life can reduce replacement frequency and associated waste
- Compact DIN rail construction helps minimise switchboard material and installation space
- Metal and thermoplastic components can be separated for responsible end-of-life recycling where local facilities permit
