Key Features
  • 150kA high breaking capacity for high-fault-level installations
  • Magnetic-only trip unit suited to motor protection schemes
  • 800A frame with an 800A rated current
  • Three-pole configuration for three-phase systems
  • Suitable for integration with contactors and thermal overload relays
  • Compatible with optional accessories including auxiliary contacts, shunt trip, undervoltage release and motor operator
  • Designed for switchboard and industrial power distribution applications
Professional Installation Requirements
  • Installation, commissioning and protection coordination should be completed by a licensed electrician or suitably qualified electrical professional. The magnetic-only release does not provide thermal overload protection, so a correctly selected thermal overload relay or equivalent motor protection device is required where applicable. Install in accordance with the manufacturer's instructions, applicable wiring rules and local certification requirements.
Applications
  • Switchboard mains protection
  • Industrial three-phase distribution systems
  • Motor protection arrangements using a contactor and separate thermal overload relay
  • High prospective short-circuit current installations
  • Commercial and industrial power distribution assemblies
Standards & Compliance
  • Applicable Australian standard: AS/NZS IEC 60947.2 for low-voltage circuit-breakers; verify product certification, RCM requirements and suitability for the intended Australian installation before use
Environmental Benefits
  • Long service life and replaceable accessories can reduce equipment replacement waste
  • Metal components can generally be recovered and recycled at end of service life
  • Low-voltage switchboard protection supports safer, more reliable operation of electrical systems
