FAQs
This is a dry-type distribution transformer with a 919X frame and 201X wiring connection, designed for indoor use in switchgear rooms or controlled spaces. Plan for adequate clearance, proper ventilation, and routing to 480 V primary and 208Y/120 V secondary circuits. If outdoor exposure is anticipated, consider WS35 Weathershield options and enclosure protection to maintain performance.
The unit offers taps at +2.5% and -2.5% to adjust secondary voltage in response to feeder drops or load swings. This improves voltage regulation, reduces nuisance tripping of sensitive drives, and maintains consistent equipment performance across shifts and equipment starts.
Yes. With a 300 kVA rating and a 480 V to 208Y/120 V secondary, it supports motor drives, control panels, and power-intensive equipment common in data centers and manufacturing floors. Its dry-type construction and copper windings enhance reliability, while the shielded design minimizes EMI in densely packed equipment rooms.
The transformer is UL Listed and NEMA TP-1 compliant, signaling compliance with safety and efficiency standards important for industrial installations. These certifications help meet procurement criteria, support regulatory alignment, and simplify audit processes for regulated facilities and OEM integration.
Warranty is Eaton Selling Policy 25-000, one year from installation or eighteen months from shipment, whichever occurs first. Copper windings and robust dry-type construction contribute to reliable operation with reduced maintenance needs, while the insulated design supports long service life in demanding environments.
