Professional Installation Requirements
  • Installation, testing and replacement must be performed by a licensed electrician in accordance with AS/NZS 3000, manufacturer instructions and applicable electrical safety regulations.
Applications
  • Three-phase final subcircuits
  • Commercial and residential distribution boards
  • HVAC and refrigeration equipment supplies
  • Motors, pumps and other inductive loads with moderate starting current
  • Electrical circuits requiring combined overcurrent and 30 mA residual current protection
Standards & Compliance
  • AS/NZS 61009.1 for residual current operated circuit-breakers with integral overcurrent protection
  • AS/NZS 3000 for selection and installation within Australian and New Zealand electrical installations
Environmental Benefits
  • Conforms to EU RoHS 2.0 environmental requirements, restricting specified hazardous substances
  • Long electrical and mechanical endurance can reduce replacement frequency and associated waste
  • Combines circuit-breaker and residual-current protection in one device, reducing panel component count
