Feature → Business Impact → Application: General-Purpose Encapsulated Transformer with 15 kVA rating and single-phase, 60 Hz operation enables scalable power delivery to control panels and machine feeders, minimizing voltage drop and improving reliability in automated lines. This capacity supports a wide range of equipment loads, reducing the need for intermediate transformers and simplifying design. Application: manufacturing lines and packaging systems where consistent voltage is critical for sensors, drives, and PLCs. Feature → Aluminum windings reduce weight and thermal stress compared with copper equivalents, lowering shipping costs and easing field handling. This improves installation efficiency and long-term maintenance costs. Application: process equipment and on-site power distribution where weight and thermal performance matter. Feature → EP encapsulation and a NEMA 3R enclosure deliver moisture resistance and rugged protection, enabling indoor-outdoor use and resistance to dust and incidental moisture. Business impact: fewer enclosure breaches, extended service life, and better reliability in damp or outdoor environments. Application: outdoor switchgear housings and exposed electrical rooms without compromising safety. Feature → 538A wiring connection and a compact 14.12 x 16.35 x 23.31 in footprint with a 369 lb weight provide straightforward integration into existing racks or panels, reducing retrofit work. Business impact: faster installation, reduced mounting complexity, and predictable fit in shared spaces. Application: panel builders and retrofit projects where space and connector compatibility are critical. Feature → 115°C temperature rise rating and 60 Hz operation support sustained loading during peak demand events, improving stability under transient loads. Application: peak-shaving scenarios and equipment startup in industrial facilities. Feature → UL Listed certification and a one-year warranty deliver assurance of safety compliance and post-purchase protection, mitigating risk for plant operators and procurement teams. Application: procurement and compliance reviews where traceable safety credentials are mandatory.

FAQs
The S40N14S15N is a single-phase, 15 kVA transformer with a 538A wiring connection and a compact footprint (14.12 in L x 16.35 in W x 23.31 in H). It fits common control panel configurations and switchgear racks, allowing straightforward mounting and wiring. With aluminum windings and a NEMA 3R enclosure, it tolerates indoor-outdoor installations and reduces raceway adjustments, saving install time and downstream wiring costs.
Expect reliable 60 Hz operation with a primary voltage range of 190–440 V and a secondary of 110/220 V, supporting a broad range of loads from sensors to actuators. The 115°C rise rating means the transformer can handle brief load surges without thermal overload, improving uptime in peak demand periods. This combination is ideal for strip-mining panels, packaging lines, and automation controllers.
Yes. The enclosure specifies NEMA 3R protection and the unit is designed for indoor-outdoor use (weathershield: Indoor-Outdoor). UL Listed safety certification further ensures compliance with industry standards. The result is a robust transformer that can live in damp, dusty, or exposed environments without compromising performance or safety.
The S40N14S15N carries UL Listed certification, a hallmark of safety compliance for electrical products. Its NEMA 3R enclosure adds weather-resistant capability, supporting outdoor installation. For procurement and maintenance, these certifications simplify safety audits, acceptance testing, and regulatory reviews while helping to minimize risk and warranty disputes.
With 15 kVA capacity, aluminum windings, and a dependable 60 Hz rating, the transformer reduces energy losses and weight-related handling costs compared with heavier copper designs. The rugged encapsulation and outdoor-ready enclosure lower maintenance cycles and downtime. The UL listing and 1-year warranty provide financial protection against unexpected failures, supporting a favorable ROI through improved uptime and lower operational risk.
