Key Features
  • 800A moulded case circuit breaker for high-current low-voltage installations
  • Three-pole configuration for three-phase systems
  • Magnetic-only instantaneous short-circuit protection
  • Adjustable magnetic trip range for motor circuit protection
  • 36kA ultimate and service breaking capacity at AC 380/400/415V
  • Suitable for switchboard mains and feeder protection
  • Suitable for isolation
  • Designed for use with contactors and thermal overload relays in motor protection arrangements
Professional Installation Requirements
  • Installation, commissioning and adjustment must be performed by a licensed electrician or suitably qualified electrical professional. Select and install the breaker in accordance with the manufacturer's instructions, AS/NZS 3000, AS/NZS 60947.2 and the switchboard assembly requirements. A magnetic-only release does not provide overload protection and must be coordinated with suitable motor overload protection where required.
Applications
  • Main switchboard protection
  • Three-phase feeder protection
  • High-current distribution boards
  • Motor circuit short-circuit protection when coordinated with a contactor and thermal overload relay
  • Industrial and commercial power distribution systems
Standards & Compliance
  • AS/NZS 60947.2 for low-voltage circuit-breakers, subject to verification of the specific Australian-approved product variant
  • AS/NZS 3000 for selection and installation within electrical installations
  • AS/NZS 61439 may apply to the completed low-voltage switchboard assembly
Environmental Benefits
  • Long mechanical and electrical service life can reduce replacement frequency and product waste
  • Reusable moulded-case construction supports maintenance and replacement of accessories rather than complete system replacement
  • Magnetic-only protection avoids standby electronic control circuitry and associated electronic component waste
  • Can support reliable operation of high-efficiency motor and power distribution systems when correctly coordinated
