Key Features
  • Magnetic-only protection for high fault-current and motor circuit applications
  • 50 kA short-circuit breaking capacity at 415 V AC
  • Compact 125 A frame with a 63 A magnetic trip rating
  • Three-pole construction for three-phase systems
  • Suitable for fixed installation in switchboards and distribution equipment
  • Magnetic-only configuration requires separate overload protection where required
  • Top or bottom line connection options and vertical or horizontal installation capability
Professional Installation Requirements
  • Installation, selection and commissioning must be performed by a licensed electrician in accordance with applicable wiring rules, manufacturer instructions and the complete protection-coordination design. Magnetic-only protection does not replace required overload protection for motor circuits.
Applications
  • Motor short-circuit protection when used with a separate overload relay
  • Three-phase switchboard mains and submain protection
  • Industrial and commercial low-voltage distribution boards
  • High prospective fault-current applications requiring 50 kA interruption capacity
  • Isolation and circuit protection in compatible switchboard assemblies
Standards & Compliance
  • Applicable product standard: AS/NZS IEC 60947.2 for low-voltage circuit-breakers
  • Installation should comply with AS/NZS 3000 and the requirements applicable to the complete switchboard assembly
Environmental Benefits
  • Long mechanical and electrical service life can reduce replacement frequency and associated material waste
  • Metal terminals and conductive components are recyclable at end of service life
  • Compact construction reduces material use compared with larger-frame circuit breakers
  • Repairable and accessory-compatible switchboard equipment can support longer system service life
