Key Features
  • 800A rated current in an 800A frame
  • 100kA high breaking capacity for high-fault-level installations
  • Magnetic-only trip unit provides instantaneous short-circuit protection
  • Suitable for motor protection when used with a contactor and thermal overload relay
  • Three-pole configuration for three-phase systems
  • Adjustable magnetic trip threshold
  • Suitable for switchboard mains and industrial power distribution
  • Can be installed vertically or horizontally with top or bottom line entry
Professional Installation Requirements
  • Installation, testing and commissioning must be performed by a licensed electrician in accordance with AS/NZS 3000, the switchboard manufacturer's requirements and applicable local regulations. Magnetic-only protection does not provide overload protection, so a suitable thermal overload relay or equivalent motor protection must be selected where required.
Applications
  • Main switchboard protection
  • Industrial power distribution
  • Three-phase motor protection systems used with a contactor and thermal overload relay
  • High fault-level commercial and industrial installations
  • Generator, transformer and feeder protection
Standards & Compliance
  • Applicable product standard: AS/NZS IEC 60947.2 for low-voltage circuit-breakers
  • Installation and switchboard integration should be assessed against AS/NZS 3000 and AS/NZS 61439 where applicable
Environmental Benefits
  • RoHS-related compliance documentation is available for the NM8N series
  • Copper, aluminium and steel components can be recovered through appropriate electrical equipment recycling streams
  • Durable construction and long electrical and mechanical life can reduce replacement frequency and product waste
