Energy efficient electrical transformers have NEMA approval
Schneider Electric announces availability of the Square D Premium 30 energy efficient transformers, which are 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’s) recently introduced Premium Efficiency Transformer Program specifications, which require 30% fewer losses than existing Department of Energy (DOE) regulations. By meeting the program’s specifications, buildings can reduce energy consumption and contribute to LEED certifications. Additional features and benefits: mounting dimensions consistent with Square D TP1 and general purpose transformers; 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); 3-in. clearances from all ventilated openings; and routine terminal location and wiring compartment designs that meet the National Electrical Code (NEC) bending requirement.
Large terminals allow lugs to handle cables of 250% on the primary and 125% on the secondary. Neutral terminals allow cables for 250% of nameplate current accommodating loads requiring 200% neutrals.
Transformer line includes distribution transformers, non-linear transformers and harmonic mitigating transformers and can reduce power consumption regardless of the loading profile.
