Companies trying to cut data center costs have typically tended to focus on approaches like energy consumption, air flow management and server consolidation to achieve their goals. Some though are beginning to explore the use of low voltage, small footprint electrical equipment to optimize floor space utilization and make more room available for revenue-generating IT equipment in their data centers. One strategy used by data centers worldwide has been the UL-listed UL891 Form 4b Type 7 design switchgear.

Switchgear based on the UL891 Form 4b Type 7 design standard offers a compact, fully compartmentalized alternative to switchgear based on the legacy UL891 standard commonly found in U.S. data centers.  The UL-listed UL891 Form 4b Type 7 equipment have fully segregated busbars and functional components that allow maintenance engineers, machine operators, fitters and others to access all internal components in a safe manner. Data center operators in other parts of the world have been using UL891 Form 4b Type 7 switchgears to improve data center efficiencies, but the concept is only just beginning to catch on in the United States.

The reason is the different standards for electrical equipment in the United States and Europe. Most low voltage switchgears in the U.S. are based on the UL891 or 1558 standards defined by the National Electric Manufacturers Association (NEMA). In Europe however, LV switchgears are based on the International Electro-technical Commission (IEC) standard.

The standards evolved from completely different design philosophies and approaches to industrial safety. The IEC standard is firmly rooted in a post, World War-II application-oriented design approach focused primarily on reducing potential safety hazards. The U.S. standard, on the other hand, emphasizes performance under extreme conditions and the ability for equipment to survive beyond designed life spans. As a result of these differences, equipment based on the two standards vary in footprint, component segregation approaches, and safety design. The UL891 Form 4b Type 7 switchgears offer several benefits over gear-based on NEMA standards, including these top 10 advantages:

  • UL-listed Form 4b Type 7 switchgears are much smaller in size than equipment based on legacy UL891 and 1558 and allow more space for computer equipment in the data center.
  • All components in a UL-listed UL891 Form 4b Type 7 switchgear are fully segregated and compartmentalized, thereby offering a higher level of protection for internal components compared to a typical legacy UL891 or UL891 component.
  • The component segmentation prevents electrical arcs from damaging other components in the switchgear.
  • The separation improves human safety by providing protection against contact with live parts.
  • The compartmentalization allows for better, error-free performance compared to legacy UL891 equipment.
  • Switchgear based on the UL-listed UL891 Form 4b Type 7 standard offer at least as good as or even better price performance than legacy UL891 systems.
  • Because of the inherent safety features in devices based on the European standard, companies may not need to use as much personal protective equipment (PPE) for some task. Saving time and money.
  • The isolation of components results in longer equipment life and better quality compared to equipment based on the legacy UL891 standard.
  • UL-listed UL891 Form 4b Type 7 equipment also suffers lower downtimes stemming from component failures and human errors.
  • The inherent safety of the design contributes to increased workplace safety not just among those who need access to the equipment, but also to other personnel in the data center.

With continued rise in data center operations cost, mission critical facility operators should consider the cost savings of the UL-listed UL891 Form 4b Type 7, which is equal to, or better than, the legacy UL891 design.  Not to mention the added advantages with differentiating workplace safety measures.
