Key Features
  • Three-pole protection for three-phase circuits
  • Magnetic-only release provides instantaneous short-circuit protection without thermal overload protection
  • Suitable for motor protection when coordinated with a contactor and separate thermal overload relay
  • 125A frame accommodates the 100A rated current
  • 36kA short-circuit breaking capacity at common low-voltage operating voltages
  • Suitable for fixed switchboard installation
  • Top or bottom line entry supported
  • Manual isolation and circuit protection in one device
Professional Installation Requirements
  • Installation, selection and testing must be performed by a licensed electrical contractor. Because this is a magnetic-only MCCB, a separate overload protection device is required where motor or cable overload protection is needed. Install and coordinate the device in accordance with AS/NZS 3000, AS/NZS 60947.2 and the switchboard manufacturer's requirements.
Applications
  • Three-phase motor feeder short-circuit protection
  • Industrial control panels and motor control centres
  • Switchboard incomers and submains where overload protection and selectivity are separately engineered
  • Commercial and industrial low-voltage distribution systems
  • Protection and isolation of high-fault-level circuits
Standards & Compliance
  • Applicable Australian product standard: AS/NZS 60947.2 for low-voltage circuit breakers
  • Manufacturer states compliance with the IEC 60947 series; verify Australian market approval, RCM marking and installation suitability before use
Environmental Benefits
  • Durable reusable protection device can extend the service life of connected motors, cables and switchboard equipment
  • Serviceable fixed-installation design can reduce replacement frequency and associated waste
  • Supports efficient equipment protection and maintenance in industrial electrical systems
