Encapsulated construction with aluminum windings boosts durability and heat management, enabling stable voltage under peak loads. This reduces insulation wear and helps prevent unexpected outages in busy automation cabinets. It's well suited for control panels, factory automation, and machine builds where space is limited. NEMA 3R enclosure provides indoor-outdoor protection, allowing mounting in harsh environments or exposed locations with minimal additional enclosures. The protection reduces installation time and cost while maintaining safety for operators and equipment. With a 2 kVA rating and a 277 V to 120 V secondary, this transformer supports PLC power, relays, sensors, and motor-control circuits at 60 Hz. The single-phase design simplifies wiring and minimizes harmonics, improving overall system efficiency and reliability. The 176 frame and compact footprint (8 in L × 14.25 in H × 7.69 in W) fit crowded panels, while 511DD wiring streamlines field connections; UL Listed certification confirms safety and compliance for industrial installations. Designed for ease of installation and maintenance, the Eaton S27N12S02 reduces risk of downtime and supports cost-effective retrofits in existing control architectures. It’s a proven choice for panel builders, OEMs, and end users prioritizing rugged, long-life low-voltage transformers.

FAQs
Start with confirming the 176 frame fit and the 8 in L × 14.25 in H × 7.69 in W footprint. Mount the unit securely, then connect the primary 277 V and secondary 120 V lines using the 511DD wiring configuration. Ensure the enclosure offers NEMA 3R protection and adequate clearance for cooling. Adhere to local electrical codes and Eaton installation guidelines to minimize heat buildup and ensure safe operation.
The transformer provides a 2 kVA rating with a primary voltage of 277 V and a secondary voltage of 120 V. It operates at 60 Hz and is a single-phase design, suitable for supplying control circuits, relays, sensors, and PLC power in industrial applications.
Yes. It features a NEMA 3R enclosure and an Indoor-Outdoor weather shield, enabling reliable operation in exposed or semi-exposed spaces. This makes it a strong candidate for outdoor panels, factory floors near equipment, and other environments where protection from the elements is essential.
The S27N12S02 is UL Listed, confirming safety and compliance with applicable standards. The unit’s rugged construction and NEMA 3R enclosure further support regulatory and performance requirements for industrial power distribution and control applications.
The encapsulated aluminum-wound design reduces insulation wear and heat-related losses, contributing to longer service life and fewer outages. Its compact footprint and simple wiring (511DD) lower installation time and retrofit costs, delivering a favorable total cost of ownership for panel builders, OEMs, and end users.
