Key Features
  • High 150kA short-circuit breaking capacity at 380–415V AC
  • Magnetic-only trip unit suited to motor short-circuit protection when coordinated with an overload relay
  • 400A frame accommodates 315A rated current

  • Suitable for switchboard mains and industrial distribution applications
  • Fixed surface-mount construction with screw-terminal connections
  • Optional control, signalling and protection accessories available
  • Supports vertical or horizontal installation with top or bottom line entry
Professional Installation Requirements
  • Installation, selection, coordination and testing should be carried out by a licensed electrical contractor in accordance with applicable Australian requirements. Magnetic-only protection does not provide overload protection, so motor applications require appropriate thermal overload protection and coordination.
Applications
  • Switchboard mains protection
  • Three-phase low-voltage distribution boards
  • Industrial motor short-circuit protection with a separate overload relay
  • Commercial and industrial electrical equipment protection
  • Main and sub-main circuit protection
  • Electrical isolation and fault protection in industrial installations
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 is the applicable Australian/New Zealand product standard for low-voltage circuit-breakers; verify product conformity, local registration and installation requirements before use.
  • The NM8N series is specified by CHINT to IEC/EN 60947-2; Australian acceptance should be confirmed for the specific supply and installation.
Environmental Benefits
  • Long service life can reduce replacement frequency and associated material waste
  • Metallic components can be recovered through appropriate electrical equipment recycling streams
  • RoHS documentation is available for the NM8N product series, supporting restricted-substance compliance
  • Reliable fault protection can help reduce damage to downstream electrical equipment and extend system service life
