  • Magnetic-only trip provides short-circuit protection without thermal overload protection
  • 125 A rated current with a 125 A frame size
  • 36 kA Icu and Ics at common 380–440 V AC operating voltages
  • Instantaneous magnetic trip set at 10 times the rated current
  • Suitable for isolation when installed in accordance with the applicable electrical design
  • Optional auxiliary, alarm, shunt-trip and undervoltage accessories are available for the NM8N range
Professional Installation Requirements
  • Installation, selection of protective settings and connection to a switchboard or motor circuit must be performed by a licensed electrician. Because this is a magnetic-only breaker, a correctly selected overload relay or equivalent motor overload protection is required where overload protection is needed. Install and commission in accordance with AS/NZS 3000 and the manufacturer's instructions.
Applications
  • Motor feeder short-circuit protection used with a contactor and thermal overload relay
  • Switchboard mains and submain protection
  • Industrial and commercial low-voltage distribution boards
  • Protection of three-phase equipment and machinery circuits
  • Isolation and fault protection in fixed electrical installations
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 for low-voltage circuit-breakers
  • AS/NZS 3820 for essential safety requirements for electrical equipment
  • AS/NZS 3000:2018 for electrical installation and switchboard wiring requirements
Environmental Benefits
  • Long service life helps reduce replacement frequency and associated material waste
  • Moulded-case construction includes recyclable metallic and thermoplastic components at end of service life
  • Replaceable accessories and coordinated external overload protection can extend the useful life of the installation
