FAQs
Mounting should account for the unit's 16 in height, 10.38 in width, and 9.89 in depth, with a total weight of approximately 104 lb. Use a sturdy base or rack, provide adequate clearance for cooling and wiring, and ensure vibration is minimized. The NEMA 3R enclosure supports outdoor installation, and wiring connections use the 2D configuration for straightforward panel integration.
The transformer is a single-phase, 3 kVA unit with a 480 V primary and a 120/240 V secondary. It operates at 50–60 Hz, includes 2 at -5% FCBN taps, and employs aluminum windings. The enclosure supports indoor-outdoor use (NEMA 3R), with a 115 °C rise rating to handle moderate ambient temperatures.
Yes. With a 3 kVA rating and 480 V to 120/240 V output, it serves common control panel needs and distribution boards in industrial settings. The 2D wiring option and -5% tap capability provide flexible integration, while the NEMA 3R enclosure supports outdoor or harsh environments, and UL Listed ensures safety compliance.
The unit is UL Listed, confirming safety compliance for industrial electrical equipment. It features a rugged NEMA 3R enclosure suitable for indoor-outdoor use, and is designed for 50/60 Hz operation. No CE or IP ratings are listed in the provided data, so verify project requirements if those certifications are essential.
The transformer is covered by Eaton's policy: one year from installation or eighteen months from shipment, whichever occurs first. Maintenance is typically low, thanks to a sealed encapsulated design and aluminum windings. The combination reduces routine service downtime and long-term replacement risk, contributing to a favorable return on investment in ongoing plant operations.
