Feature: K-Factor nonlinear ventilated design enhances cooling under high non-linear loading. Business Impact: Reduces heat buildup, improves reliability, and lowers cooling costs in dense electrical rooms. Application: Ideal for manufacturing lines and control panels with harmonic-rich loads. In practice, installers report fewer hot spots and longer insulation life when this ventilation strategy is leveraged. Feature: DOE2016 Efficient compliance signals lower energy losses throughout operation. Business Impact: Decreases ongoing energy consumption and supports corporate sustainability targets. Application: Suitable for facilities with energy-performance mandates and incentive programs. Real-world data show lower total cost of ownership when energy efficiency is prioritized in power infrastructure. Feature: 150 kVA rating with 3-phase, primary 480 V to secondary 208Y/120 V configuration. Business Impact: Streamlines compatibility with standard distribution gear and minimizes space when used as a mid-size step-down. Application: Fits typical plant mains and control-system panels, enabling compact, scalable distribution layouts. Feature: UL Listed certification provides validated electrical safety and reliability. Business Impact: Reduces procurement risk and accelerates compliance audits, improving project timelines. Application: Essential for regulated industrial environments and projects with supplier qualification requirements. Feature: High temperature rise rating of 150 °C supports rugged operation in hot manufacturing environments. Business Impact: Improves reliability in ambient-intensive settings and reduces the need for oversized cooling. Application: Suitable for hot floors or compact electrical rooms where air exchange is limited. Feature: Substantial weight and robust frame (1200 lb, Frame 943) with standard wiring connection (305K). Business Impact: Enables durable, long-life installations with predictable mounting and termination practices. Application: Requires appropriate handling equipment and trained installation teams; compatibility with common enclosure layouts enhances retrofit feasibility.

Yes. The unit carries UL Listed certification for electrical safety and complies with DOE2016 Efficient guidelines, supporting energy-performance targets. This combination helps shorten procurement approvals and reduces regulatory risk during commissioning while delivering proven performance in industrial settings.
The transformer weighs about 1200 lb and uses a ventilated frame (Frame 943). Plan for forklift or crane-assisted placement and secure mounting in a ventilated electrical room or outdoor enclosure, as required. Ensure adequate clearance for ventilation, wiring access with a 305K connection, and routing to compatible 480 V and 208Y/120 V distribution circuits.
Key specs include a 150 kVA rating, three-phase operation, primary 480 V, secondary 208Y/120 V, 150 °C temperature rise, and DOE2016 Efficient compliance. Confirm wiring terminations, enclosure suitability, and available space for 31.5 in depth, 51 in height, and 34.5 in width to ensure proper fit and service accessibility.
Yes, the K-Factor nonlinear ventilated design is intended for nonlinear loads common in modern factories. Regular maintenance should include inspection of ventilation paths, thermal monitoring, UL-listed safety checks, and periodic insulation resistance tests. Keeping the cooling pathways clear helps maintain efficiency and extends service life in high-harmonic environments.
