Key Features
  • High 70 kA short-circuit breaking capacity
  • Magnetic-only trip unit for instantaneous short-circuit protection
  • 250 A frame with a 200 A rated current
  • Three-pole configuration for three-phase circuits
  • Suitable for motor protection when coordinated with separate overload protection
  • Can be used for switchboard, commercial and industrial power distribution applications
  • Supports isolation where the installation and selected configuration permit
Professional Installation Requirements
  • Installation, selection and testing must be carried out by a licensed electrician. The magnetic-only release does not provide overload protection, so motor circuits generally require correctly coordinated overload protection. Installation must comply with applicable Australian wiring, switchboard and equipment requirements.
Applications
  • Three-phase motor circuit short-circuit protection
  • Switchboard mains and sub-main protection
  • Commercial and industrial power distribution
  • Low-voltage electrical panels
  • Industrial machinery and motor control assemblies
Standards & Compliance
  • IEC 60947-2 is the applicable product standard basis; Australian installations should verify conformity with AS/NZS IEC 60947.2 and applicable RCM requirements
  • Installation within electrical installations should comply with AS/NZS 3000
  • Assembly integration into a switchboard should be assessed against AS/NZS 61439 where applicable
Environmental Benefits
  • Durable moulded-case construction can support a long service life and reduce replacement waste
  • Copper and other metallic components can be recovered through established electrical-equipment recycling streams
  • Provides reliable fault protection that can help limit damage to downstream electrical equipment during short-circuit events
