FAQs
Install the S29N11S82 in a suitable enclosure with adequate clearance for the 54 frame and 8 lb weight. Connect the primary 208V to the designated input terminals and attach the 120/240V secondary to the control circuits. Since there are no taps, ensure the input voltage remains stable to avoid rating deviations. Use proper insulation and follow all local codes for indoor-outdoor installations.
The unit features a NEMA 3R enclosure that protects against moisture and dust, allowing safe operation in exposed locations. Its UL Listed certification confirms safety compliance, while the aluminum coil provides robust durability. Together, these factors enable reliable performance in environments where weather and contamination could impact traditional transformers.
This is a single-phase transformer with a primary voltage of 208 V and a secondary voltage of 120/240 V. The voltage rating is 0.1 kVA, operating at 60 Hz with a temperature rise of 115 °C. It uses a 26 A wiring connection and has no taps, making it straightforward for fixed-voltage control applications in standard automation setups.
The transformer follows Eaton’s warranty policy 25-000, providing one year from installation or eighteen months from shipment, whichever comes first. This warranty supports lower long-term maintenance risk and helps justify the initial value by protecting against early-life defects in mission-critical control circuits.
Prioritize a clean, dry mounting surface for the NEMA 3R enclosure and ensure adequate ventilation to manage the 115 °C rise under load. With aluminum coil construction and a compact 4 x 8.91 x 4.11 inch footprint, plan for limited space in panel layouts. Confirm compatibility with existing Eaton power management components to maximize performance and simplify future upgrades.
