Eaton S48G11S25LS47 General-Purpose Transformer - UL Listed
Part Number: S48G11S25LS47
Quick Summary
Eaton S48G11S25LS47 encapsulated transformer provides 480 V to 120/240 V power for industrial controls and equipment across facilities. Many plants struggle with bulky, noisy units that complicate indoor-outdoor installation, increasing space needs and maintenance costs. UL Listed safety, NEMA 3R enclosure, and indoor-outdoor rating enable versatile deployment, weather resistance, and regulatory compliance across plant floors and outdoor equipment pits. With a 25 kVA rating, single-phase design, and 47 dB low-noise operation, it improves efficiency, reduces energy waste, and simplifies retrofit projects. Designed for 60 Hz operation with 480 V primary and 120/240 V secondary, it supports standard control panels and motor starters. Additionally, the aluminum coil and rugged enclosure reduce lifecycle costs and downtime in harsh environments.

FAQs
The S48G11S25LS47 uses a NEMA 3R enclosure and is rated for indoor-outdoor installations, enabling installation on outdoor pads or in protected outdoor equipment spaces. Plan for a suitable mounting surface, appropriate clearance for heat dissipation, and a lifting method due to its 712 lb weight. Ensure proper wiring with the S452V connection and consider wind and rain exposure in outdoor locations.
The -5% FCBN tap setting provides a voltage tap for slightly lowering the secondary voltage to compensate for elevated line voltages or long feeder runs. This helps keep the 120/240 V output within tolerance for equipment, reducing nuisance trips and protecting control panels and motors. Use it during commissioning when feeder resistance or supply conditions warrant tighter regulation.
Yes. With a 25 kVA rating and single-phase operation, this transformer is well suited for medium-sized loads such as motors, lighting, and control panels in industrial environments. The 480 V primary and 120/240 V secondary support common control gear, and the unit’s 60 Hz rating aligns with standard facility power systems, simplifying integration into existing electrical rooms.
This transformer is UL Listed, which provides safety certification for electrical components and assemblies. It also features a NEMA 3R enclosure suitable for indoor-outdoor use and an indoor-outdoor weather rating (Weathershield), giving installers flexibility for mixed environments. These certifications help streamline regulatory compliance and reduce risk in critical power applications.
