Professional Installation Requirements
- Installation, selection and commissioning must be carried out by a licensed electrician in accordance with the manufacturer's instructions, applicable electrical installation requirements and the relevant Australian standards. A magnetic-only breaker does not provide thermal overload protection, so a correctly selected motor overload device may also be required.
Applications
- Motor circuit short-circuit protection
- Three-phase switchboard protection
- Industrial distribution boards
- Commercial electrical panels
- Low-voltage feeder and equipment protection
- Motor starter and control assemblies
Standards & Compliance
- AS/NZS IEC 60947.2:2015 is the applicable Australian/New Zealand standard for low-voltage circuit-breakers; verify the specific product certification, local approval and RCM requirements before installation in Australia
- AS/NZS 3000 applies to selection, installation and verification within Australian electrical installations
Environmental Benefits
- RoHS documentation is available for the NM8N product family, supporting restriction of hazardous substances
- Durable moulded-case construction can reduce replacement frequency and associated material waste
- Metal and thermoplastic components may be recoverable through appropriate electrical equipment recycling streams at end of service life
Warranty Information
CHINT's general warranty policy provides 27 months from the date of manufacture for other low-voltage apparatus sold through authorised channels.
