Key Features
  • High 150kA short-circuit breaking capacity
  • Magnetic-only trip unit designed for motor protection applications
  • Compact 250A frame with a 160A rated current
  • Three-pole configuration for three-phase systems
  • Suitable for switchboard mains, feeders and motor circuits
  • Front, rear and DIN-rail mounting options available within the NM8N range
  • Positive isolation and manual switching capability
Professional Installation Requirements
  • Installation, selection and commissioning must be performed by a licensed electrician. A magnetic-only breaker does not provide overload protection, so a correctly selected motor overload relay or equivalent protection is required where applicable. Install and verify settings in accordance with AS/NZS 3000, the manufacturer’s instructions and the switchboard design.
Applications
  • Three-phase motor short-circuit protection
  • Motor control centres and industrial control panels
  • Switchboard mains and submain protection
  • High-fault-level commercial and industrial distribution systems
  • Feeder protection where magnetic-only tripping is required
Standards & Compliance
  • AS/NZS IEC 60947.2: Applicable Australian/New Zealand product standard for low-voltage circuit-breakers
  • AS/NZS 3000: Applicable wiring and installation requirements; final compliance depends on the complete installation and local approval requirements
Environmental Benefits
  • Long mechanical and electrical service life can reduce replacement frequency and associated waste
  • Metal and thermoplastic components may be recoverable through appropriate electrical equipment recycling streams
  • Supports reliable motor and distribution protection, helping reduce damage-related equipment replacement
