- Compatible with cable, U-type busbar and pin-type busbar connections
- Accepts optional auxiliary, alarm, shunt-release and under-voltage accessories
- Resettable protection reduces the need for fuse replacement
Professional Installation Requirements
- Installation, testing and commissioning must be carried out by a licensed electrician in accordance with applicable Australian electrical installation requirements, including AS/NZS 3000. Confirm fault levels, discrimination, conductor sizing and local approval markings before installation.
Applications
- Three-phase domestic distribution boards
- Commercial switchboards and consumer units
- Industrial distribution panels
- Motor, pump, compressor and transformer circuits with high starting current
- Control systems and electrical equipment requiring D-curve overcurrent protection
Standards & Compliance
- IEC/EN 60898-1 product standard
- AS/NZS 60898.1 is the applicable Australian/New Zealand standard for household and similar AC circuit-breakers; verify that the supplied variant carries the required Australian approval and RCM marking
- Installation within Australia should comply with AS/NZS 3000
Environmental Benefits
- Resettable circuit protection can reduce replacement waste compared with single-use fuses
- Long mechanical and electrical service life may reduce replacement frequency
- Metallic and thermoplastic components can be separated for appropriate end-of-life recycling
- Supports reliable energy distribution and protection of connected electrical equipment
