Schneider Electric Introduces Premium 30 Energy Efficient Transformers with NEMA Approval.


Schneider Electric has announced availability of the Square D Premium 30 Energy Efficient Transformers. The new line of transformers is designed to help reduce lost energy, exceed minimum efficiency program standards, and provide optimal performance and superior quality in commercial, industrial, healthcare, educational, and government buildings.

The new line of transformers comply with the National Electrical Manufacturers Association’s (NEMA) recently introduced Premium Efficiency Transformer Program specifications, which require 30% fewer losses than existing Dept. of Energy (DOE) regulations and will help utilities, commercial buildings, and industrial plants incorporate high-efficiency electrical transformers into their operations. By meeting the program’s specifications, these buildings can reduce energy consumption and contribute to LEED certifications in commercial, industrial, and institutional facilities.

Additional features and benefits of the Premium 30 Energy Efficient Transformers include:

  • Easy to Spec and Install - Mounting dimensions consistent with Square D TP1 and general purpose transformers
  • Safe and Reliable - All units tested per NEMA ST-20 and NEMA TP-2 requirements in a laboratory that participates in UL’s Client Data Test Program (UL File DA643)
  • Compact Footprint - Three inch clearances from all ventilated openings require less overall installation floor space compared to the industry standard of six inches
  • Intuitive Design - Routine terminal location and wiring compartment designs meet the National Electrical Code (NEC) bending requirement. Large terminals allow lugs to handle cables of 250 percent on the primary and 125% on the secondary. Neutral terminals allow cables for 250% of nameplate current accommodating loads requiring 200% neutrals.

Schneider Electric’s Square D Premium 30 Energy Efficient Transformers include distribution transformers, non-linear transformers and harmonic mitigating transformers and can reduce power consumption regardless of the loading profile.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
