FAQs
This transformer is a 1-phase unit rated at 50 kVA with a 240 x 480 V primary and 120/240 V secondary, designed for straightforward integration into standard panel boards and switchgear racks. Its vented construction and copper windings support reliable heat dissipation, while the tap options help match system voltage. Confirm enclosure clearance and mounting footprint per IEC/UL guidelines before retrofit.
The NT20P11F5016CU uses a primary voltage of 240 x 480 V and provides a secondary voltage of 120/240 V. Taps allow voltage adjustments at +5%, -5%, +2.5%, and -2.5% to compensate for load variations and line drops, supporting stable operation of sensitive loads and drive systems.
Yes, the NT20P11F5016CU carries DOE 2016 Efficient Notes in its catalog information. This designation reflects improved energy performance and reduced standby losses. When paired with proper sizing and loading practices, it helps facilities meet corporate energy goals and regulatory requirements while maintaining reliable power distribution for critical equipment.
The transformer provides taps at +5%, -5%, +2.5%, and -2.5% to correct supply voltage under varying load and connection conditions. Adjusting taps minimizes voltage drop along feeders, improves motor and drive performance, and reduces overheating. Use test loads and voltage measurements to select the optimal tap setting for each feeder or zone.
Ideal applications include plant power distribution, automation panels, and motor-control centers requiring stable 120/240 V secondary from a 240/480 V source. Plan routine visual and thermal inspections, verify tap positions during seasonal load changes, and maintain enclosure cleanliness to preserve cooling performance.
