Confirm supply fault levels, neutral arrangement, protection coordination, cable termination and required Australian compliance markings before installation.
Applications
  • Mains-to-generator changeover systems
  • Commercial and industrial standby power systems
  • Main switchboards and distribution boards
  • Data centres and critical power installations
  • High-rise buildings and infrastructure facilities
  • Three-phase emergency and backup power systems
Standards & Compliance
  • IEC 60947-1 and IEC 60947-6-1 product standards are specified for the NXZ series
  • AS/NZS 3010:2017 applies to electrical installations incorporating generating sets and automatic changeover devices
  • AS/NZS 3000:2018 applies to the associated electrical installation and switchboard wiring
  • Verify the applicable Australian certification and RCM requirements for the specific imported unit before installation
Environmental Benefits
  • Durable circuit-breaker construction can reduce replacement frequency and electrical equipment waste
  • Metal and thermoplastic components may be recoverable through appropriate electrical equipment recycling streams
