Encapsulated design provides moisture and dust resistance, extending service life in dirty or damp environments. The S40N14S03CEL24 reduces field failures by isolating windings and minimizing oil exposure, delivering consistent voltage during transient loads. This is ideal for industrial control panels, motor starter assemblies, and distribution enclosures where reliability directly affects uptime. Broad primary-voltage compatibility and clear secondary outputs support flexible system integration. With primary options of 190/200/208/220/380/400/416/440 V and a secondary of 110/220 V, it accommodates common power-distribution schemes without custom wiring. The 3 kVA rating supports a wide range of control circuits and small-motor feeds, improving energy efficiency and reducing the need for multiple transformers on the line. Durable materials and enclosure rating reduce maintenance and service costs. Aluminum windings offer good thermal performance while staying lightweight, and the 115 °C rise rating provides headroom under peak loads. The NEMA 3R indoor-outdoor enclosure and 24-inch leads simplify installation in both indoor cabinets and outdoor-rated spaces, aligning with atmospheric and regulatory requirements. Installation and compliance advantages come from UL Listed and CE Marked certification, along with the 24-inch leads and a robust mounting frame (177). The unit's single-phase, 60 Hz operation matches standard industrial power, making retrofit straightforward. Its wiring connection is specified as 538A, enabling predictable control-panel wiring with minimal field modifications. Operational value includes predictable performance, reduced downtime, and easier maintenance. The transformer’s rugged construction minimizes replacements, while the included warranty policy supports long-term procurement planning. For engineers sourcing a reliable, general-purpose encapsulated transformer, this Eaton model delivers a tested solution that integrates with standard control-system components and meets common regulatory expectations.

FAQs
Install the S40N14S03CEL24 using its 24-inch leads for simple pre-wiring, secure mounting on a compatible frame (177) within a NEMA 3R enclosure. Verify the primary supply is within 190–440 V and tie the 110/220 V secondary to the control circuits. Follow UL/CE labeling and ensure proper clearance for heat dissipation and servicing.
The unit accepts a wide primary range of 190, 200, 208, 220, 380, 400, 416, and 440 V, with a secondary of 110/220 V. This flexibility supports various European and North American bus configurations, allowing you to supply control circuits and low-voltage controls without multiple units. It is a single-phase, 60 Hz transformer suitable for common industrial networks.
Yes. It features a NEMA 3R enclosure designed for indoor-outdoor use and an indoor-outdoor Weathershield specification. The aluminum windings and encapsulated construction provide moisture resistance, while the 115 °C rise rating supports operation under elevated loads in variable climates. UL Listed and CE Marked certifications further support compliance in mixed environments.
The S40N14S03CEL24 is UL Listed for safety and CE Marked for European compliance, with a NEMA 3R enclosure supporting outdoor or harsh indoor environments. These certifications simplify regulatory approvals, facilitate installation in multinational facilities, and help ensure reliability in industrial control applications where safety and standards conformance are critical.
Expected ROI stems from reduced downtime and simplified wiring thanks to a single, versatile 3 kVA transformer with 24-inch leads and a durable NEMA 3R enclosure. Aluminum windings and a robust encapsulated design lower maintenance needs, while UL CE certifications reduce compliance risk. The unit’s reliability supports longer service life and predictable maintenance budgeting for control systems.
