Professional Installation Requirements
- Installation, commissioning and connection to mains or generator supplies must be performed by a licensed electrician in accordance with applicable electrical regulations, manufacturer instructions and AS/NZS 3000. Correct neutral switching, fault protection, discrimination and generator interlocking must be verified for the installation.
Applications
- Mains-generator automatic changeover systems
- Commercial standby-power installations
- Industrial power-distribution systems
- Data, communications and other critical-load backup supplies
- Building services and infrastructure requiring automatic source transfer
- Three-phase switchboards and generator control panels
Standards & Compliance
- Applicable equipment standard: AS/NZS IEC 60947.6.1:2015 for low-voltage transfer switching equipment; the specific installation must also comply with AS/NZS 3000 and relevant local requirements.
Environmental Benefits
- Supports continued operation of critical electrical systems during mains interruptions, reducing disruption and potential equipment losses
- Durable switchgear construction can extend service life and reduce replacement waste
- Metallic and thermoplastic components can generally be recovered through appropriate electrical-equipment recycling streams at end of life
- Enables controlled generator changeover for efficient use of standby power systems
