Mini Power Centers

Mini Power Centers

Mini Power Centres combine three individual components into one NEMA Type 3R enclosure: a pre-wired primary and secondary main breaker, an encapsulated single-phase (Type EP) or three-phase dry-type transformer or dry-type shielded transformer, and a secondary distribution load center with main breaker. Inter-connecting wiring is completed at the factory. Mini Power Centers are used wherever there is loads requiring 208Y/120V, three-phase or 120/240V single-phase. • An encapsulated core & coil transformer • A circuit panel with 24, 30 or 42 branches wired to a secondary of a transformer • Primary circuit breaker installed/wired from the factory • Secondary main breaker installed/wired from the factory • CSA Enclosure Type 3R or NEMA 3R • Hinged circuit panel (can be padlocked) Standard • Indoor/Outdoor application • Wall mounting • ASA 61 grey color • Wall mounting • Knock outs are provided for easy access • All live parts are enclosed • CSA Certified • UL Listed • Manufactured and assembled in ISO 9001 certified facilities Optional • Frequency • Shielding • Color

2016. Minimum efficiency level for Dry-Type Transformers in the USA

The U.S. Department of Energy (DOE) is adopting a new set of minimum efficiency standards for Dry-Type Transformers that are sold into the United States. The new rule takes effect on January 1st, 2016, and it is for the United States only. The rule replaces the current minimum efficiency levels, which are known as the “NEMA TP-1” or “DOE 2010” efficiency levels with DOE 2016 effciency level.
With DOE 2016, the impact on cost approximately 20 – 50% more.
