Key Features
  • Automatically transfers a load between normal and alternative power sources
  • Suitable for mains-generator and other standby power changeover applications
  • Four-pole switching provides neutral switching for suitable installations
  • High-breaking-capacity version for systems with higher prospective fault current
  • Class CB design based on circuit-breaker switching technology
  • Manual and automatic operating modes with mechanical interlocking
  • Padlockable off position for safe maintenance isolation
  • Type A standard controller provides essential automatic transfer control
  • Designed for three-phase, four-wire power systems
Professional Installation Requirements
  • Installation, commissioning and connection to mains or generator supplies must be performed by a licensed electrician in accordance with AS/NZS 3000, AS/NZS 3010 and the equipment installation instructions. Type A controller does not provide generator start/control functionality, so generator starting arrangements must be separately engineered where required.
Applications
  • Mains-to-generator changeover systems
  • Commercial and industrial standby power distribution
  • Building services and essential-load switchboards
  • High-rise and infrastructure backup power systems
  • Three-phase four-wire electrical installations
Standards & Compliance
  • AS/NZS IEC 60947.6.1:2015 for transfer switching equipment
  • AS/NZS 3010:2017 for electrical installations incorporating generating sets
  • AS/NZS 3000:2018 for electrical installation and wiring requirements
Environmental Benefits
  • Supports continuity of supply and efficient use of standby generation by transferring loads only when required
  • Durable switching construction and rated endurance can reduce replacement frequency and equipment waste
  • Metallic electrical components are generally recoverable through appropriate electrical equipment recycling streams
