SafeGear ANSI Air-insulated MCC
Medium voltage motor control center up to 7.2 kV
SafeGear Motor Control Centers are a complete line of UL-listed arc-resistant motor control centers in ANSI/NEMA ratings. They are designed for heavy industrial applications, including mining, power plants, steel mills, petrochemical and marine applications, transportation and general industry.
Product Scope
- Rated voltage: ... Up to 7.2kV
- Rated current: ... 400A, Rated contactor current: ... 720A
- Rated short time current: ...50 kA @ 2s
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
Features
- 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 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
