Professional Installation Requirements
- Installation and connection to mains electrical circuits must be performed by a licensed electrician in accordance with applicable Australian wiring rules, manufacturer instructions and local regulatory requirements.
Applications
- Domestic electrical distribution boards
- Commercial switchboards
- Lighting circuits
- Resistive load circuits
- Overload and short-circuit protection for final subcircuits
- Low-voltage AC control and distribution panels
Standards & Compliance
- AS/NZS 60898.1 is the applicable Australian/New Zealand product standard for miniature circuit-breakers used in household and similar installations; CHINT product documentation specifies IEC/EN 60898-1.
- Installation should also comply with AS/NZS 3000 wiring rules and applicable state or territory electrical regulations.
Environmental Benefits
- Long mechanical service life can reduce replacement frequency and associated material waste
- Modular DIN rail construction allows individual circuit protection devices to be replaced without replacing the complete switchboard assembly
- Metal components and thermoplastic housing materials can be separated for appropriate recycling at end of service life
