Key Features
  • Magnetic-only trip unit for short-circuit protection in motor circuits
  • 125A frame with a 32A rated current
  • 150kA ultimate short-circuit breaking capacity at 380/400/415V AC
  • Three-pole construction for three-phase systems
  • Suitable for motor protection applications when used with appropriate overload protection
  • Supports isolation functionality
  • Compact moulded-case construction for switchboard installation
  • Zero arcing distance design
Professional Installation Requirements
  • Installation, selection and connection should be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and the requirements of the complete motor protection system. A separate overload protection device is required because the magnetic-only trip unit does not provide thermal overload protection.
Applications
  • Motor protection circuits with separate overload relays
  • Industrial and commercial switchboards
  • Three-phase equipment protection
  • Main and sub-main switchboard protection where the available fault level requires high breaking capacity
  • Low-voltage power distribution systems
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 for low-voltage circuit-breakers
Environmental Benefits
  • Moulded-case electrical components and metallic conductor parts can be separated and directed to appropriate recycling streams at end of service life
  • High breaking capacity and durable construction can help reduce equipment damage and replacement waste following short-circuit events
  • Long mechanical and electrical service life supports reduced replacement frequency
