Copper windings provide superior conductivity, reducing I2R losses and improving overall efficiency, which translates to lower operating costs over the life of the transformer. NEMA 2 enclosure delivers dependable protection in standard shop and plant environments, enabling safer operation and easier service access. The K-Factor 13 designation helps manage harmonics in modern loads, reducing overheating and extending insulation life in critical applications. DOE 2016 efficiency compliance ensures energy savings and regulatory alignment across facilities pursuing energy performance programs. A 75 kVA three-phase rating supports scalable loads, while 480 V to 480Y/277 V output compatibility simplifies integration with common motor drives and control panels. The copper-to-copper construction and shielded design bolster reliability in harsh environments, and the mounting options (floor or wall, upright only) speed up installation and service planning.

FAQs
The N48M47T7516CU is designed for floor or wall mounting, upright only, in a ventilated space. Plan for adequate clearance for cooling, access for servicing, and compatibility with a 480 V primary feeding a 480Y/277 V secondary. Verify the surrounding environment meets NEMA 2 protection requirements and is within the enclosure's rated protection category to maintain performance and safety.
The transformer carries a K-Factor of 13, indicating enhanced tolerance to harmonic currents common in modern electrical systems. This results in reduced insulation stress, lower overheating risk, and improved reliability in facilities with nonlinear loads such as drives and power converters. It supports sustained performance in contaminated or high-harmonic environments.
Yes. The unit is UL Listed, confirming compliance with safety standards, and meets DOE 2016 efficiency requirements, which translates to lower no-load and loaded energy losses. These certifications support regulatory compliance, reduced energy costs, and safer operation in compliant industrial installations.
The transformer has a 480 V primary and a 480Y/277 V secondary, configured for three-phase operation. This enables seamless integration with common industrial mains and control systems, supporting motors, drives, and control panels that require 480 V delta or 480Y/277 V wye connections. The 75 kVA rating ensures adequate sizing for typical manufacturing and process loads.
Copper windings and a shielded design reduce resistance losses and protect winding integrity, contributing to lower life-cycle costs. DOE 2016 efficiency and UL Listing support regulatory compliance and energy savings, yielding faster payback in facilities with energy management programs. Its robust enclosure and mounting options simplify installation, maintenance access, and long-term reliability.
