  • Suitable for three-phase final subcircuits requiring neutral connection
  • 10kA rated short-circuit breaking capacity
  • Visual contact-position indication
  • Bottom connection with cable, U-type busbar or pin-type busbar compatibility
  • Compact modular design for switchboard installation
Professional Installation Requirements
  • Installation, testing and maintenance must be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable state or territory electrical requirements.
Applications
  • Three-phase final subcircuits
  • Commercial and industrial distribution boards
  • HVAC and refrigeration equipment supplies
  • Motor and pump circuits with moderate starting current
  • Protection of electrical circuits against overload, short circuit and earth leakage
Standards & Compliance
  • AS/NZS 61009.1 for residual current circuit-breakers with integral overcurrent protection
  • AS/NZS 3000 for selection, installation and verification within Australian electrical installations
Environmental Benefits
  • Conforms to EU RoHS 2.0 requirements restricting hazardous substances
  • Integrated protection can reduce equipment damage and premature replacement caused by electrical faults
  • DIN-rail modular construction supports replacement of the protective device without replacing the complete switchboard assembly
  • Metal components and selected thermoplastics can be recovered through appropriate electrical equipment recycling streams
