FAQs
Plan for the FR942 frame footprint (24 in L x 30.5 in W x 43 in H) and a 673 lb weight. Ensure access to 283B wiring connections and taps, with clearances for maintenance and service, and choose floor or wall mounting based on space and cabinet alignment.
DOE 2016 Efficient compliance reduces core and copper losses compared with older designs, delivering lower total cost of ownership. Savings vary by load profile, but facilities with continuous operation and energy-management initiatives typically experience meaningful reductions in energy consumption over the transformer’s life.
Yes. With a NEMA 2 indoor enclosure and copper windings, it is designed for indoor plant rooms, switchgear cabinets, and control panels where dust and moisture are controlled within spec.
The primary is 480 V and the secondary is 220Y/127 V. Tap settings of 2 at +2.5% and 4 at -2.5% allow fine voltage regulation to accommodate load variations and ensure equipment stays within tolerance under fluctuating supply conditions.
UL Listed certification confirms electrical safety compliance, while DOE 2016 efficiency supports energy-code alignment. The K-13 modification option provides customization for specific installation requirements, enhancing procurement flexibility for mission-critical systems.
