Key Features
  • 150kA high interrupting capacity at 380–415V AC
  • Magnetic-only trip unit intended for motor protection applications
  • 250A frame with a 200A rated current
  • Three-pole configuration for three-phase systems
  • Suitable for switchboard mains and feeder protection
  • Compatible with optional auxiliary, shunt, undervoltage and operating accessories
  • Compact moulded-case construction with insulation safety features
Professional Installation Requirements
  • Installation, adjustment and testing must be carried out by a licensed electrical contractor. The magnetic-only trip does not provide overload protection, so a correctly rated external motor overload relay or equivalent protection device is required. Installation must follow the manufacturer's instructions, applicable switchboard requirements and AS/NZS 3000.
Applications
  • Three-phase motor short-circuit protection
  • Motor control centres and industrial machinery
  • Switchboard mains and feeder protection
  • Commercial and industrial power distribution
  • High fault-level low-voltage distribution systems
Standards & Compliance
  • AS/NZS IEC 60947.2:2015, the applicable Australian and New Zealand standard for low-voltage circuit-breakers; verify product certification and RCM requirements before installation
Environmental Benefits
  • RoHS declarations are available for the NM8N product range, supporting restriction of hazardous substances
  • Durable moulded-case construction and high mechanical life can reduce replacement frequency and material waste
  • Copper and metal components are recoverable through appropriate electrical equipment recycling streams
