Feature → Business Impact → Application: K-Factor 13 with an electrostatic shield reduces harmonic currents and improves power quality, delivering smoother operation for sensitive loads and extended equipment life on critical manufacturing lines. This enables tighter regulatory compliance and lower maintenance costs in plants where harmonic distortion can affect sensors and drives. Application: data centers, process facilities, automated assembly lines. Feature → Business Impact → Application: Copper windings and rugged NEMA 2 enclosure provide robust protection in indoor environments with moderate exposure to dust and moisture, supporting long service intervals and safer installations. Application: manufacturing floors, control rooms, and switchgear rooms. Feature → Business Impact → Application: 60 Hz frequency, 225 kVA rating, and primary 480 V to secondary 208Y/120 V configuration support standard industrial power distribution, reducing the need for bespoke transformers and enabling seamless integration with existing switchgear. Application: warehouses, OEM equipment, and plant-wide power networks. Feature → Business Impact → Application: Tap size options (+2.5% at two taps, -2.5% at four taps) offer precise voltage regulation and improved load matching, minimizing voltage drop and the risk of equipment mis-operation. Application: motor drives, PLCs, and control panels. Feature → Business Impact → Application: Electrostatic shield and 220 °C insulation enhance reliability in environments with higher electrical noise and temperature rise, enabling safer operation and longer intervals between service cycles. Application: high-density control cabinets and process lines. Feature → Business Impact → Application: DOE 2016 Efficient and WS62 weather-shield capability optimize energy use and environmental protection, reducing operating costs and protecting internal components in appropriate indoor environments. Application: facilities aiming for energy targets and better enclosure performance.

FAQs
This unit is floor-mounted with a substantial footprint and weight (3345 lb). Ensure a reinforced concrete base or pad, adequate clearances for cooling and service access, and appropriate lifting provisions. The NEMA 2 enclosure protects against indoor moisture, while the 283B wiring connection supports standard field terminations. Verify electrical clearances per local codes and create a dedicated space for routine maintenance and inspection.
Key specs include 225 kVA rating, 60 Hz frequency, primary voltage 480 V, secondary voltage 208Y/120 V, copper windings, and a 80 °C rise insulation rating. Tap settings include 2 at +2.5% and 4 at -2.5% to fine-tune voltage. Compliance notes include DOE 2016 Efficient and UL Listed status, with an electrostatic shield option for improved power quality.
Yes, within indoor, protected spaces it is well-suited thanks to a NEMA 2 enclosure and copper windings designed for durability. The electrostatic shield modification further mitigates noise and harmonics, while insulation rated at 220 °C supports reliability under elevated temps. WS62 weathershield and other accessories can extend protection in more challenging indoor settings.
The unit is UL Listed and DOE 2016 Efficient, with 10 CFR Part 431 compliance noted in catalog documentation. These certifications help meet safety and energy-efficiency requirements for regulated facilities, reduce audit risk, and support corporate sustainability goals across industrial operations.
Energy efficiency from DOE 2016 compliance lowers operating costs through reduced losses, while the compact electrostatic shield and copper windings extend service life by improving load tolerance and reducing heat. The combination of robust protection, standard wiring, and voltage-tap options minimizes replacement frequency and downtime, delivering measurable savings over the equipment’s life cycle.
