Eaton S25N12S05CU Transformer - Encapsulated 115°C rise
Part Number: S25N12S05CU
Quick Summary
The Eaton S25N12S05CU transformer delivers reliable 1-phase power isolation for control panels in industrial automation setups. In today’s environments, incorrectly sized transformers lead to downtime, excess heat, and reduced equipment life. Look for CE and UL certifications where required, RoHS compliance, and manufacturer datasheets to confirm current certification status. With a 5 kVA rating, copper windings, and encapsulated construction, it supports compact layouts, easy installation, and lower lifecycle costs in general-purpose applications. This design enables predictable performance, simplified sourcing, and long-term reliability for panel builders and end-users alike. The result is improved uptime, reduced maintenance, and a clearer return on investment across automation deployments.

FAQs
The S25N12S05CU is designed for single-phase 220/120 V systems and encapsulated form factors, enabling straightforward drop-in replacement in many standard control panels. It supports typical mounting footprints and terminal configurations used in industrial cabinets, reducing the need for specialized enclosures and easing panel wiring during commissioning.
Verify power rating (5 kVA), phase (1-phase), input/output voltages (220 V to 120 V), winding type (copper), and thermal rise (115°C). Confirm enclosure integrity for your environment, and reference Eaton datasheets for any derating requirements under certain ambient conditions or enclosure constraints.
Yes. With a 5 kVA rating and 220-120 V output, it supports control logic, PLCs, and automation modules typical of motor control centers and automation racks. Its encapsulated design aids reliability in shared spaces and simplifies wiring, making it a practical choice for centralized control architectures.
General-purpose encapsulated transformers commonly require CE and UL markings for many markets. For this model, certification status should be verified in Eaton’s current datasheets or by contacting the manufacturer directly, as listed in the product documentation and downloadable specifications.
Minimal routine maintenance is typical due to encapsulation and copper-windings design, which reduces moisture ingress and contamination risk. ROI benefits come from higher panel reliability, reduced downtime, easier installation, and lower lifecycle costs associated with predictable performance in automated environments.
