Key Features
  • Three-pole protection for low-voltage AC systems
  • Magnetic-only trip unit provides short-circuit protection without thermal overload protection
  • 125A frame accommodates a 25A rated current
  • 36kA ultimate and service short-circuit breaking capacity at 380–440V AC
  • Suitable for motor circuit short-circuit protection where overload protection is provided separately
  • Can be installed vertically or horizontally with top or bottom line entry
  • Optional auxiliary, shunt-release, undervoltage-release and motor-operated accessories are available for the NM8N series
Professional Installation Requirements
  • Installation, selection of protective settings and connection to a switchboard or motor circuit should be performed by a licensed electrician in accordance with AS/NZS 3000 and the manufacturer's installation instructions. Magnetic-only protection does not replace separate overload protection where required.
Applications
  • Motor circuit short-circuit protection with separate overload protection
  • Industrial switchboards
  • Commercial electrical distribution boards
  • Low-voltage AC control and power circuits
  • Machinery and motor control panels
  • Main or sub-main protection where the system design permits magnetic-only tripping
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 – applicable product standard for low-voltage circuit-breakers and MCCBs
  • AS/NZS 3000 – installation and wiring requirements for electrical installations
Environmental Benefits
  • Metallic conductive components and the thermoplastic housing can be separated for responsible end-of-life recycling
  • Long mechanical service life can reduce replacement frequency and associated material waste
  • Magnetic-only operation avoids continuous electronic sensing power consumption
