Key Features
  • 150kA high breaking capacity for high prospective fault-current applications
  • Magnetic-only trip unit designed for motor circuit short-circuit protection
  • Three-pole configuration for three-phase systems
  • 800A frame accommodates a 630A rated current
  • Suitable for switchboard mains, industrial distribution and motor feeder applications
  • Supports vertical or horizontal installation and top or bottom line entry
  • Designed for isolation and low-voltage AC distribution systems
Professional Installation Requirements
  • Installation, adjustment and commissioning must be performed by a licensed electrician in accordance with AS/NZS 3000 and the manufacturer's instructions. Because the magnetic-only trip does not provide thermal overload protection, suitable motor overload protection must be provided separately where required.
Applications
  • Industrial switchboard mains protection
  • Three-phase motor feeder short-circuit protection
  • Commercial and industrial low-voltage distribution systems
  • High fault-level power distribution installations
  • Motor control centres and large machinery supply circuits
Standards & Compliance
  • AS/NZS 3000:2018 Electrical installations, including switchboard and protective-device installation requirements
Environmental Benefits
  • Long service life can reduce replacement frequency and associated material waste
  • Metal and thermoplastic components may be recoverable through appropriate electrical equipment recycling streams
  • High breaking capacity supports durable protection of downstream electrical equipment, helping reduce premature equipment replacement
