FAQs
Plan for floor or wall mounting in a secured service area, allowing upright orientation as specified. Expect a substantial footprint (30.5 in wide by 43 in high) and weight around 692 lb. Ensure adequate ventilation, access for connections (Wiring 295B), and proximity to loads in a NEMA 2 enclosure environment to maintain performance and serviceability.
Yes. The transformer features a K-Factor of 13 and a nonlinear ventilated design to mitigate harmonics, alongside copper windings and an electrostatic shield to reduce EMI. This combination supports stable operation for sensitive drives, CNC systems, and robotics with reduced risk of nuisance tripping and control instability.
The unit provides a 480 V primary and 240 V secondary in a three-phase configuration. It supports delta connections, specifically noted as 480 to 240 DELTA, enabling compatibility with legacy equipment and certain plant electrical designs while maintaining efficient transformation at 60 Hz.
The N48M24B4516CU comes UL Listed and complies with DOE 2016 Efficient requirements, with catalog notes referencing 10 CFR Part 431 (2016) Efficient. These certifications help ensure regulatory alignment, energy efficiency incentives, and simplified procurement for projects with strict compliance criteria.
Maintenance needs are typical of industrial power transformers, with emphasis on routine inspections of enclosure integrity, cooling pathways, and connections. The energy efficiency and reduced heat generation from DOE 2016 compliance contribute to lower operating costs over time, while the rugged copper-windings design supports longer service life and lower replacement frequency in demanding environments.
