Professional Installation Requirements
- Installation, testing and connection to mains electrical circuits must be performed by a licensed electrician in accordance with AS/NZS 3000, the switchboard manufacturer's requirements and applicable local regulations.
Applications
- Domestic distribution boards
- Commercial electrical switchboards
- Lighting and general-purpose final circuits
- Control panels and light industrial distribution systems
- Protection of circuits requiring B-curve overcurrent protection
Standards & Compliance
- IEC/EN 60898-1 product standard
- AS/NZS 60898.1:2024 is the applicable Australian/New Zealand standard for AC miniature circuit-breakers of this type; verify current approval and marking requirements before installation
- AS/NZS 3000 applies to selection and installation within Australian electrical installations
Environmental Benefits
- Modular DIN rail construction allows replacement of the individual protective device without replacing the complete switchboard assembly
- Metal and thermoplastic components can be separated for recycling at end of service life
- Long mechanical service life can reduce replacement frequency and associated material waste
- RoHS documentation is available for the NB1-63H product range
