CENTERLINE^® Low Voltage Motor Control Centers with ArcShield™

CENTERLINE 2100 Motor Control Centers with ArcShield



Reduce your risk of arc flash injury through the use of the industry leading arc containment design, which has been tested to meet the arc resistant standards for medium voltage equipment, IEEE C37.20.7: IEEE Guide for Testing Medium-Voltage Metal- Enclosed Switchgear for Internal Arcing Faults.

ArcShield enhances the CENTERLINE 2100 Motor Control Center (MCC) and is the first low voltage MCC to offer arc-containing features. ArcShield helps provide you with Type 2 accessibility and improves protection for your personnel against internal arcing faults. With Type 2 accessibility, personnel are shielded at the front, rear and sides of the enclosure in the unlikely event of an arcing fault.

Arc resistant baffles for the CENTERLINE 2100 MCCs with ArcShield allow you to have an arc resistant MCC with a wider range of MCC units, even units that require venting, such as variable frequency drives (VFDs). Arc resistant baffles allow air flow to help dissipate the heat and still provide Type 2 accessibility.

CENTERLINE 2100 MCCs with ArcShield are available on the quick delivery program; allowing your order to go directly to the factory and ship in as little as four weeks.

Contain Arc Flashes

Arc-containment door latches help deliver an extra level of protection by allowing pressure relief and keeping the doors from detaching from the structure. Manual or automatic shutters and insulated bus covers help reduce fault propagation within your MCC. The lower horizontal bus ratings and incoming protection sized for your MCC, help reduce the amount of arc flash energy in your application. By containing an arc flash, your potential exposure to hazardous conditions can be reduced.

Reduce Electrical Shock Hazards

CENTERLINE 2100 MCCs are designed to enhance safe operation by helping isolate you from potentially hazardous voltages by providing a solid grounding system and helping minimize potential electrical shock hazards. Additional options such as IntelliCENTER^® software, DeviceNet™ ports, blown fuse indicators, exterior windows on unit doors, infrared inspection ports and finger-safe component barriers can help you create a safer working environment by reducing your potential to make contact with energized components.

CENTERLINE 2500 Motor Control Centers with ArcShield



The CENTERLINE 2500 MCC is designed to meet the needs of your global facilities operating in Latin America, Asia, Europe and other areas of the world where motor control centers must meet IEC standards. With more intelligent components and more options than other MCC manufacturers, you get a total power, control and information solution packaged for your local specifications, built on a common platform.

CENTERLINE 2500 MCCs with ArcShield offers you better protection against harmful arc flash hazards. Using a CENTERLINE 2500 MCC with ArcShield helps protect your personnel if an arc flash were to occur within an MCC.

CENTERLINE 2500 MCC with ArcShield provides personnel and assembly protection per IEC/TR 61641:2008 for arcing durations up to 300 ms (available for systems at 415V (max), with 65 kA (max) available current).

In combination with the standard safety features built into every CENTERLINE 2500 MCC, choosing ArcShield provides additional benefits, including:

• Enclosures with no front ventilation
  
• Pressure relief system designed to exhaust gases through the top of the enclosure, away from personnel
  
• Arc containment latches on all doors capable of withstanding the high internal pressure generated by an arc blast
  
• Insulated power bus closing plates included at the ends of each MCC lineup
  
• For even more protection, optical and current sensing technology for use with crowbar or shunt trip devices is available as an option.
  

Arc-free Zones

Arc-free zones are part of a circuit within the assembly where it is not possible to apply an ignition wire without destroying the insulation material on conductors.

The CENTERLINE 2500 standard arc-free zones include:

• Vertical busbars are completely enclosed by the insulated bus support and cover
  
• Automatic shutters are supplied with standard product offering
  
• Supply side of outgoing withdrawable units utilizes cabling that meets the requirements of IEC 60439-1 (7.5.5.3)
  
• Insulated stab housing provides a separate, isolated pathway for each phase
  

IntelliCENTER Technology



Minimize Entry into Arc Flash Boundary

IntelliCENTER technology helps enhance personnel safety

• Advanced diagnostics of IntelliCENTER software provide remote access to your MCC data for troubleshooting, minimizing your need for entry in the arc flash boundary zone
  
• With the ability to remotely monitor MCC, you can perform many routine maintenance tasks without "suiting up," reducing personnel exposure to hazardous energy levels
  
• IntelliCENTER Software can warn of failures before they occur – increasing your ability to respond proactively before a hazardous situation occurs
