Eaton Specification Sheet - P48G28B1518CUB
The P48G28B1518CUB delivers a robust 15 kVA three-phase transformer with a 480 V primary and 208Y/120 V secondary, housed in a NEMA 3R enclosure for indoor and outdoor installations. This feature translates into a reliable power backbone for control cabinets and industrial panels, reducing downtime and improving system availability. Copper coil material ensures durable, high-efficiency operation with excellent thermal characteristics, supporting an 80 °C rise for consistent performance in demanding environments. The unit is wall-mountable with bolt-on assembly and uses the M48G1H wiring connection, enabling straightforward installation and maintenance in tight spaces. With 18 spaces and a 13.62 in depth, 32.63 in width, and 40.01 in height, footprint-conscious designs can still deliver substantial power capacity without compromising safety or access. Tap size of 2 at -5% FCBN provides flexibility to accommodate voltage variations common in industrial facilities. The 60 Hz frequency rating aligns with standard North American power systems, while the sound level classification under NEMA ST-20 helps with acoustical planning in noise-sensitive environments. Overall, the combination of UL, CSA, IEEE, and ANSI certifications supports compliance-driven procurement and risk management, reducing the need for multiple third-party verifications and accelerating project timelines. The unit’s 619 lb weight signals a solid, vibration-resistant install suitable for demanding machine rooms or utility rooms, while 18 spaces enable scalable distribution for growing control architectures. This makes the P48G28B1518CUB a practical choice for panel builders seeking reliable, code-compliant three-phase transformers that balance performance, protection, and ease of installation.
