  • Compatible with optional CHINT NM8N accessories
Professional Installation Requirements
  • Installation, connection and commissioning must be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable switchboard requirements. Magnetic-only protection does not provide motor overload protection and should be coordinated with an appropriate overload device where required.
Applications
  • Main and sub-main protection in industrial switchboards
  • Three-phase power distribution systems
  • Motor control circuits with separate overload protection
  • Commercial and industrial switchgear assemblies
  • High prospective fault-current installations
Standards & Compliance
  • AS/NZS IEC 60947.2 for low-voltage circuit-breakers
  • AS/NZS 3820 essential safety requirements where applicable to in-scope electrical equipment
  • AS/NZS 3000 for installation and wiring practices
Environmental Benefits
  • Durable moulded-case construction supports extended service life and reduces replacement waste
  • Metal components can be recovered for recycling at end of service life
  • Resettable circuit protection avoids routine replacement of fuses after fault operation
