- Domestic distribution boards
- Commercial switchboards
- Lighting circuits
- Heating and other predominantly resistive loads
- Overload and short-circuit protection for low-voltage AC final circuits
Standards & Compliance
- AS/NZS 60898.1 is the applicable Australian/New Zealand product standard for miniature circuit-breakers for household and similar AC installations; verify local certification and installation suitability before use.
- AS/NZS 3000 applies to the electrical installation and wiring system in which the circuit-breaker is installed.
Environmental Benefits
- Thermal-magnetic protection can limit damage to wiring and connected equipment, reducing premature replacement waste.
- Durable modular construction supports extended service life and reduces the frequency of component replacement.
- Metallic and thermoplastic components may be recoverable through appropriate electrical equipment recycling streams at end of life.
