Mission critical businesses can’t always trust the power grid to supply energy. Rather, they require specialized equipment to meet their critical power needs in addition to normal power distribution equipment.

This often includes automatic transfer systems, UPS systems, onsite generation, emergency power equipment, filtered power distribution, surge protection, static transfer, specialized cooling systems and interfaces to other building management systems.

Designing, installing and managing systems of this complexity is no small task. Schneider Electric combines best-in-class products and expertise with application-specific services to provide tightly coordinated, one-stop solutions to businesses in which power availability is a requirement – not an option.

With hundreds of successful installations and growing, Schneider Electric specializes in meeting the specific needs of data centers. Today, Square D® brand equipment appears in the data centers of some of the nation’s largest companies and government agencies. Whether Tier I or Tier IV, we design and deliver an ultra-reliable, tiered system that addresses even the greatest data center challenges.

PowerPact D-Frame Mission Critical Circuit Breaker

The Square D® Mission-Critical Breaker is designed for use as a main breaker in a Power Distribution Unit (PDU). Incorporating thermal magnetic selective tripping functions, the breaker assures faults on a single branch circuit do not cascade causing a shutdown of an entire PDU.

Masterpact NW Circuit Breaker

Rated for use on battery UPS systems, transit applications and DC backup systems in power plants and substations.

Square D Switchgear

PowerZone 4 LV Switchgear

The primary advantages found in ANSI-rated switchgear are the structure and breaker short-time withstand ratings (short circuit current withstand for 30 cycles).

When properly adjusted, this allows main and feeder breakers to coordinate with downstream protective devices to ensure the device closest to the fault clears first. This is very important when trying to coordinate with downstream main breakers in UPSs, switchgear or other downstream devices. In addition to short-time withstand ratings, other benefits such as 100% rated breakers (from 800A to 5000A frames), drawout construction and maintainability for extended life make low voltage switchgear the primary choice in data centers.

• Small, flexible footprint
• Extended maintenance intervals
• Segregated access to all wiring
• Easily added ‘smart’ functionality including communications interfaces and power monitoring and control capability
• Available up to 5000A bus rating
• Micrologic® trip units with power monitoring, control and communications
• Optional PLC-based auto transfer schemes
• Optional Transparent Ready™ communications with PowerLogic®
• Optional Surgelogic® TVSS
• Differential ground fault option for 4W systems with multiple sources
• Arc flash application options
