FAQs
For installation, ensure indoor or semi-enclosed placement to match the totally enclosed non-ventilated design. The 918AN frame supports standard mounting footprints, and the unit uses aluminum windings with a three-phase, 60 Hz configuration. Plan for the 30.68 in L x 31.44 in W x 62.18 in H footprint and hookup to a 480 V primary with 480Y/277 V secondary, including the tap settings (+2.5% FCAN, -2.5% FCBN) for voltage regulation.
The transformer is rated at 150 kVA, three-phase, 60 Hz, with a primary voltage of 480 V and secondary voltage of 480Y/277 V. It uses aluminum windings, has a DT-3 dry-type design, and employs a frame 918AN. Tap options include 2 taps at +2.5% and 4 taps at -2.5%, enabling voltage adjustments to support stable downstream equipment operation.
Yes. The V48M47T49NV is a totally enclosed non-ventilated dry-type transformer, designed to resist dust and moisture ingress in appropriate indoor spaces. It carries UL Listing for safety compliance, aiding regulatory acceptance in regulated facilities. Ensure placement within the enclosure boundaries and implement standard maintenance as part of your preventive programs.
The primary certification stated is UL Listed, confirming safety compliance for electrical equipment. There is no CE or IP rating information provided in the specification. Refer to the Eaton datasheet for region-specific certifications and confirm local regulatory requirements before installation. This UL Listing supports procurement and acceptance testing in many industrial environments.
The unit ships with a warranty per Eaton’s Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance includes periodic insulation checks, tap changer verification, and enclosure cleanliness. The aluminum windings and DT-3 dry-type construction contribute to lower corrosion risk and reduced maintenance compared to oil-filled designs.
