Eaton S48N11S85 General purpose encapsulated transformer - UL Listed
Part Number: S48N11S85
Quick Summary
Eaton General purpose encapsulated transformer provides safe voltage conversion for control panels and industrial equipment. In tight spaces or outdoor installations, voltage stability and rugged protection are common pain points for engineers and maintenance teams. UL Listed certification ensures safety, the NEMA 3R enclosure tolerates indoor-outdoor service, and a 60 Hz single-phase design matches most control circuits. Compact 0.075 kVA rating helps reduce footprint and wiring complexity, while aluminum windings support durability and efficient heat dissipation. This combination delivers reliable performance, simple installation, and lower lifecycle costs for OEMs and maintenance teams. By aligning with UL guidelines and industry standards, it supports faster procurement and reduces risk in mission-critical systems.

Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated construction with a NEMA 3R enclosure provides rugged protection against moisture, dust, and incidental impact, improving field reliability and reducing downtime in outdoor or harsh environments. The 0.075 kVA rating is ideal for small-control loads, enabling engineers to consolidate power in compact panels while minimizing wasteful energy losses and heat buildup. Aluminum coil material offers corrosion resistance and lighter weight, translating to easier handling during installation and service, plus better heat dissipation in humid facilities. The 524H wiring connection supports consistent terminations in standard control harnesses, streamlining installation and future upgrades. With 60 Hz single-phase operation, this transformer aligns with widespread industrial controls, factory automation, and PLC power supplies, delivering predictable performance across typical manufacturing cycles. A 115 °C rise rating indicates robust thermal performance under continuous duty, supporting reliable operation in demanding applications and reducing the risk of thermal shutoffs.
