Key Features
  • 630A rated current in an 800A frame
  • 50kA short-circuit breaking capacity at AC 380/400/415V
  • Magnetic-only trip unit designed for motor protection applications
  • Three-pole configuration for three-phase power systems
  • Suitable for fixed switchboard and industrial distribution installations
  • High insulation and impulse withstand ratings
  • Modular accessory system for selected auxiliary, shunt and undervoltage releases
  • Suitable for isolation when installed and applied in accordance with manufacturer requirements
Professional Installation Requirements
  • Installation, selection and commissioning should be performed by a licensed electrician in accordance with AS/NZS 3000, applicable switchboard requirements and the manufacturer's instructions. Magnetic-only protection does not provide thermal overload protection and must be coordinated with the motor protection system.
Applications
  • Motor feeder short-circuit protection
  • Industrial switchboards and motor control centres
  • Three-phase power distribution
  • Switchboard mains and sub-mains protection where the protection scheme is correctly coordinated
  • Commercial and industrial electrical installations
Standards & Compliance
  • AS/NZS IEC 60947.2 for low-voltage circuit-breakers
  • AS/NZS 3000 for electrical installation and wiring requirements
Environmental Benefits
  • Robust moulded-case construction can support a long service life and reduce replacement waste
  • Copper and metallic conductive materials can be recovered through established electrical equipment recycling streams
  • Suitable application in efficient, properly coordinated motor and power distribution systems can help minimise avoidable electrical losses
  • Replaceable accessories and serviceable construction can extend the useful life of the breaker
