FAQs
Begin by confirming a suitable 480 V primary supply and a 524H wiring connection per Eaton documentation. Mount the unit in a compliant enclosure, ideally in a protected area to leverage the NEMA 3R rating. Connect the 480 V input to the primary terminals and land the 120/240 V secondary leads for local control circuits. Verify torque requirements and thermal clearances and perform a functional test under load to ensure voltage accuracy and stable operation.
Primary voltage: 480 V; Secondary voltage: 120/240 V; Frequency: 60 Hz; Phase: Single-phase; VA rating: 2 kVA; Coil material: Copper; Temperature rise: 115 °C; Enclosure: NEMA 3R; Weathershield: Indoor-Outdoor; Wiring connection: 524H.
Yes. The S48N11S02CU uses a NEMA 3R enclosure and is rated for indoor-outdoor use, making it suitable for environments with exposure to moisture and dust. While not explicitly IP-rated, the enclosure and weather-resistant design provide dependable operation in varied industrial settings, reducing the need for frequent enclosure changes or additional protective housing.
The transformer is UL Listed, offering recognized safety certification for industrial equipment. Eaton provides a warranty policy described as one year from installation or eighteen months from shipment, whichever occurs first. This support aligns with standard industry expectations and helps mitigate risk during early operation and commissioning.
The 2 kVA rating consolidates power needs for multiple control points, reducing part counts and panel real estate. Copper windings offer reliable thermal performance, lowering cooling requirements. The rugged indoor-outdoor enclosure minimizes weather-related downtime, while UL listing and warranty support shorten risk exposure, leading to lower total cost of ownership over the lifecycle of the installation.
