  • Three-pole construction for three-phase circuits
  • 250A frame accommodates a 160A rated current
  • Suitable for AC systems up to 690V
  • Compact moulded-case construction for switchboard and motor-control assemblies
  • Adjustable instantaneous magnetic trip range of 9–14 times rated current
  • Suitable for isolation when installed and applied in accordance with the manufacturer’s instructions
Professional Installation Requirements
  • Installation, selection and commissioning should be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer’s instructions and applicable switchboard requirements. This magnetic-only breaker does not provide thermal overload protection; a correctly selected motor overload relay or equivalent overload protection is required where motor overload protection is needed.
Applications
  • Three-phase motor short-circuit protection
  • Motor control centres and industrial switchboards
  • Switchboard feeder and branch-circuit protection where magnetic-only protection is suitable
  • Industrial machinery and motor starters
  • Commercial and industrial power distribution assemblies
Standards & Compliance
  • Designed to IEC 60947-1 and IEC 60947-2 requirements for low-voltage switchgear and circuit-breakers
  • AS/NZS IEC 60947.2:2015 is the relevant Australian/New Zealand circuit-breaker standard; verify product conformity, RCM requirements and installation suitability before use
  • Installations must comply with AS/NZS 3000
Environmental Benefits
  • Moulded-case construction and metallic conductive materials can be recovered through appropriate electrical-equipment recycling streams
  • Durable switching components and a long operating life can reduce replacement frequency and associated material waste
  • Supports efficient and reliable motor-system protection, helping reduce damage-related equipment waste
