The Square D™ brand Model 6 Low Voltage Motor Control Center (MCC) with ArcBlok™ by Schneider Electric™ is a game changer in electrical equipment protection and safety-related work practices. With ArcBlok arc isolation, the line side conductors are fully enclosed inside a cable vault, which has been tested for the ANSI/IEEE C37.20.7 requirements for arc containment. Not just a barrier, ArcBlok reduces the chance that an arc flash could occur and reduces and contains the arc energy if it does. Sensors inside the compartment continuously take thermal readings and communicate those to a mobile device, while maintenance personnel stand outside the arc flash zone to review.

Build features include:

• Steel barriers

• Lifting handles

• Bolts face outward for easy alignment

• Interior barriers separate phases

• Thermal sensors communicate data

• Absence of voltage tester

• Vents direct arc flash energy to minimize impact

Maximize customer value with the industry’s most comprehensive energy and asset management capabilities.

Standard Architectures

SIMPLE, standardized network designs create consistency and familiarity, reduce changes, accelerate startup and commissioning, and ultimately drive efficiency in existing operations and future expansions.

Reduced Lead Times

FASTER quotations, drawings, pricing, submittals, and manufacturing allow for shorter cycle times and increased flexibility to make changes later in the project as designs mature and requirements change.

Ethernet Communications

OPEN protocols in Modbus™ TCP and EtherNet/IP eliminate expensive proprietary software, hardware, and services. Both protocols provide the speed, reliability, and network services to easily and efficiently manage the entire network. Ethernet-based networks easily integrate with business systems for management across the enterprise.

Integrated Wonderware Solution

COMPLETE Wonderware solution allows the end user to perform comprehensive asset and energy management through simple, organized, and role-based screens. Power and process data can be viewed in real time or in trended report, which increases user awareness and delivers actionable data. Local or remote configuration, monitoring, and control provides optimal flexibility. Maximizing uptime, slashing troubleshooting, and delivering true predictive maintenance strategies become a reality with all the right information at the right time. Seamless integration into enterprise-level Invensys-based SCADA/DCS systems will save countless hours of unnecessary programming, engineering, and troubleshooting during both startup and operation.
