Key Features
  • Three-pole moulded case circuit breaker for low-voltage distribution systems
  • 70 kA short-circuit breaking capacity at up to 415 V AC
  • Magnetic-only trip unit provides instantaneous short-circuit protection without thermal overload protection
  • 250 A frame accommodates the 125 A magnetic release
  • Suitable for motor circuits when coordinated with separate overload protection
  • Can be installed vertically or horizontally
  • Compatible with optional auxiliary and alarm contacts
  • Compact fixed-mount design for switchboards and distribution panels
Professional Installation Requirements
  • Installation, selection and commissioning must be carried out by a licensed electrical professional in accordance with the manufacturer's instructions, applicable switchboard requirements and AS/NZS 3000. Magnetic-only protection does not provide overload protection, so motor circuits require suitable separate overload protection and coordination.
Applications
  • Switchboard mains and submain short-circuit protection
  • Industrial and commercial low-voltage distribution boards
  • Motor feeder short-circuit protection when used with a separate overload relay
  • Manufacturing plant and machinery control panels
  • Generator, transformer and power distribution installations
  • Panel-builder and OEM electrical assemblies
Standards & Compliance
  • IEC/EN 60947-2 product family requirements for low-voltage circuit-breakers
  • Applicable Australian/New Zealand reference standard: AS/NZS IEC 60947.2:2015
  • Installations and switchboard integration should comply with AS/NZS 3000 and applicable AS/NZS 61439 requirements; verify RCM and local approval before use
Environmental Benefits
  • Long service life can reduce replacement frequency and associated material waste
  • RoHS documentation is available for the NM8N product family
  • Durable moulded-case construction supports extended service in industrial switchboards
  • Enables coordinated electrical protection that can help limit equipment damage during fault events
