FAQs
The V48M28T15ZZ is designed for 480 V primary with a 208Y/120 V secondary, standard for many industrial panels and switchgear. It is a three-phase, 60 Hz transformer with aluminum windings and a DT-3 open-core construction, enabling straightforward mounting alongside existing equipment. The 15 kVA rating provides scalable support for mid-range loads without oversized installations.
At about 152 lb, the unit requires sturdy mounting and adequate ventilation in indoor environments. The open-core DT-3 design facilitates airflow, reducing thermal buildup in cabinets or enclosures. Ensure clearance for service access, compatible mounting surfaces, and compliance with UL safety practices. The 60 Hz specification aligns with common plant power systems.
Key specs include a 15 kVA rating, three-phase configuration, 480 V primary, and 208Y/120 V secondary at 60 Hz. It features aluminum windings, frame 909C, and taps at +2.5% FCAN and 4 at -2.5% FCBN for voltage regulation under load. These characteristics support stable downstream voltage and reliable device operation in automation systems.
The transformer carries UL Recognized certification, confirming conformance with essential safety standards for open-core, dry-type distribution equipment used in industrial settings. This designation supports compliance during audits and procurement cycles, giving engineers confidence in safety and performance within automated plant environments.
Warranty terms follow Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. This, combined with durable aluminum windings, a robust 909C frame, and open-core ventilation, supports predictable maintenance planning and lowers lifecycle risk for automation upgrades and panel retrofits.
