FAQs
Installation should follow standard electrical room practices for a three-phase power transformer: ensure adequate clearance for ventilation, mount on a stable surface, and connect primary 480 V delta and secondary 208Y/120 V per wiring diagrams. Use the NEMA 1 enclosure where indoor installation is required and consider the 2 AT +2.5% FCAN and 4 AT -2.5% FCBN taps for voltage regulation. UL Listed safety verification should be documented, and standard startup checks performed to confirm correct phasing and tap settings.
Key metrics include a 300 kVA rating at 60 Hz with a 150 °C rise, copper windings, 480 V delta primary, 208Y/120 V secondary, and K-Factor nonlinear ventilated design. The unit supports DOE 2016 efficiency and NEMA ST-20 sound standards, offering reliable power with reduced cooling needs. These specs make it suitable for critical loads in data centers and heavy manufacturing environments where stable voltage and efficiency matter.
Yes. The transformer is DOE 2016 Efficient compliant, with UL Listed certification, ensuring compliance with energy and safety requirements. Catalog notes reference 10 CFR Part 431 (2016) Efficient, reinforcing its alignment with federal energy efficiency standards. These certifications simplify procurement for regulated facilities and reduce risk during audits and inspections.
The K-Factor nonlinear ventilated design reduces core losses and improves cooling efficiency, contributing to lower energy costs and extended equipment life. Copper windings enhance thermal performance and reliability. Taps allow voltage adjustments to mitigate line drop, lessening wear on downstream equipment. While initial investment may be higher, long-term savings from energy efficiency and reduced downtime deliver tangible ROI in continuous-operating facilities.
The unit features a NEMA 1 enclosure for indoor protection, Case E frame, and 150 °C rise insulation, with copper windings for robust operation. Weathershield option RH6 adds environmental protection for certain sites, and UL Listing confirms safety standards. The combination of these features supports reliable operation in factory floors and electrical rooms, reducing maintenance frequency and boosting uptime.
