  • Industrial power distribution
  • Motor feeder short-circuit protection with separate overload protection
  • Motor control centres
  • Commercial and industrial feeder circuits
  • Power centre and distribution board installations

  • Applicable circuit-breaker standard: AS/NZS IEC 60947.2:2015
  • Installation should comply with AS/NZS 3000:2018 and relevant switchboard assembly requirements
Environmental Benefits
  • Durable moulded-case construction supports extended service life and reduces replacement waste
  • Reusable electrical protection device can be replaced or upgraded without replacing the complete switchboard
  • Efficient fault isolation helps limit damage to connected electrical equipment
