Key benefits 

  • Equipped with mechanical interlocks between the draw-out contactor truck and the front door to increase operation and maintenance safety
  • For optimal flexibility, the SafeGear MCC is designed to be used in combination with SafeGear metal-clad switchgear so a transition section is not required
  • Each MCC frame includes a separate, isolated low-voltage compartment that separates relays, meters and other instruments using grounded metal barriers, protecting maintenance personnel from exposure to high voltage
  • Hem bends are used throughout construction of the SafeGear MCC to increase rigidity and reduce arc propagation
  • Galvanized steel construction to enhance protection from rust, scratches and corrosion, as well as to enhance illumination properties to provide better instrument viewing

Key benefits 

  • Nominal voltage up to 7.2 kV and system voltage ratings of 2.4, 4.16, 4.8 and 6.9 kV
  • Rated main BUS current at 1,200, 2,000 or 3,000 A
  • Fully compliant with CSA and UL 347 5th Edition for Motor Control Centers and meets the IEEE C37.20.2 standard for metal-clad switchgear construction
  • Type 2B arc-resistance accessibility
  • Automatic secondary disconnects
  • No transition section required for coupling to ABB SafeGear switchgear
