FAQs
Yes, the S29N27S05 is designed for integration with Eaton power distribution setups and control panels. It features a compact footprint (9.89 in depth, 16 in height, 10.38 in width) and a 519H wiring connection, simplifying field routing. When mounting, ensure adequate clearance for heat dissipation and easy access for maintenance, with the NEMA 3R enclosure rated for indoor-outdoor use.
The transformer provides a 208 V primary and 277 V secondary configuration, operates at 60 Hz, and is rated for 5 kVA (5,000 VA) in single-phase service. This makes it suitable for supplying mid-range loads in automation panels, lighting circuits, and control gear without oversizing the distribution equipment.
The unit uses a NEMA 3R enclosure with indoor-outdoor protection, enabling outdoor installations in damp or dusty environments. Its aluminum coil and 115 °C rise insulation support reliable operation under typical industrial ambient conditions, while UL Listed certification confirms compliance with recognized safety standards.
The S29N27S05 carries UL Listed certification, indicating compliance with widely accepted safety requirements for electrical equipment. The NEMA 3R enclosure further supports environmental protection, reducing the need for additional weatherproofing in suitable installations and streamlining site approvals for panel builds.
With a 5 kVA rating, rugged encapsulated design, and UL Listed protection, this transformer offers long service life and low maintenance, minimizing downtime. A 1-year warranty (from installation date or 18 months from shipment, whichever occurs first) provides early coverage while the robust enclosure and corrosion resistance help stabilize lifetime operating costs.
