FAQs
The transformer measures 21.13 in L, 24.88 in W, 36.88 in H and weighs 416 lb, requiring adequate clearance and mounting supports in standard electrical rooms. Plan for proper ventilation, routing of primary and secondary leads, and compatible enclosure openings to maintain UL Listed safety performance. Ensure a dedicated space to support its weight and allow airflow for cooling.
K-Factor nonlinear transformers are engineered to handle harmonic currents more effectively, reducing excess heating and voltage distortion in the system. This translates to longer motor life, fewer tripping incidents, and improved power quality for drives and other non-linear loads in manufacturing or packaging environments.
Yes. The N48M28T3021CUSR is specified for 480-208Y/120 copper windings, which aligns with common mid- to high-voltage distribution schemes in industrial facilities, enabling seamless integration with existing panelboards and equipment that rely on that secondary voltage level.
The unit carries UL Listed certification, providing safety validation for installation in North American industrial environments. This certification supports regulatory adherence, supplier qualification, and faster procurement approvals, particularly in facilities with strict safety and compliance requirements.
Ventilated, copper-wind transformers typically offer lower operating losses and better thermal performance, contributing to energy savings over time. Consider routine thermal checks and periodic inspection of cooling paths. The 30 kVA rating and compact footprint support predictable maintenance planning, reducing downtime and extending asset life in continuous-operation facilities.
