Key Features
  • Three-pole moulded case circuit breaker for low-voltage AC systems
  • 125A frame with a 63A rated current
  • Magnetic-only release designed for motor short-circuit protection
  • 36kA short-circuit breaking capacity at common three-phase voltages
  • Suitable for fixed switchboard installation
  • Can be used with a contactor and separate thermal overload relay in motor starter applications
  • Supports isolation and manual circuit interruption
Professional Installation Requirements
  • Installation and commissioning should be performed by a licensed electrician in accordance with AS/NZS 3000, the manufacturer's instructions and applicable switchboard requirements. Magnetic-only protection does not provide overload protection, so motor circuits require suitable external overload protection where applicable.
Applications
  • Motor feeder short-circuit protection used with a contactor and thermal overload relay
  • Industrial and commercial switchboards
  • Three-phase distribution and feeder circuits
  • Mains or sub-main protection where the overall protection design includes suitable overload protection
  • Low-voltage AC electrical equipment requiring a 36kA MCCB
Standards & Compliance
  • AS/NZS IEC 60947.2:2015 is the applicable Australian/New Zealand standard for low-voltage circuit-breakers
  • Installation wiring and switchboard integration should comply with AS/NZS 3000 and applicable switchboard requirements
Environmental Benefits
  • Durable moulded-case construction can support extended service life and reduce replacement waste
  • Fault isolation can help limit damage to connected electrical equipment and associated material waste
  • Metal electrical components are generally recoverable through appropriate electrical equipment recycling streams
Warranty Information

CHINT's general warranty policy states 27 months from the date of manufacture for other low-voltage apparatus sold through authorised sales channels; local Australian terms and contract conditions may apply.
