Key Features
  • Magnetic-only trip unit designed for motor protection applications
  • 700A rated current within an 800A frame
  • 50kA short-circuit breaking capacity
  • Three-pole configuration for three-phase systems
  • Suitable for low-voltage distribution and motor feeder assemblies
  • Magnetic trip setting range of approximately 6300–9800A
  • Can be installed vertically or horizontally
  • Suitable for use as a main or feeder protective device where coordinated overload protection is provided separately
Professional Installation Requirements
  • Installation, testing and commissioning must be carried out by a licensed electrician in accordance with the manufacturer's instructions, applicable Australian wiring rules and switchboard requirements. Magnetic-only protection does not provide thermal overload protection, so motor installations require correctly coordinated overload protection.
Applications
  • Three-phase motor feeders
  • Industrial switchboards
  • Commercial low-voltage distribution boards
  • Switchboard mains or feeder protection
  • Motor control centres
  • Industrial plant and machinery protection
Standards & Compliance
  • AS/NZS IEC 60947.2 for low-voltage circuit-breakers
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
  • Resettable circuit protection avoids routine replacement of fuses after fault operation
