FAQs
Before wiring, confirm a three-phase 380 V primary and 208Y/120 V secondary setup, ensure the 50-60 Hz supply, verify copper windings and frame 916A, and check taps (+2.5% and -2.5%) for voltage regulation. Plan for proper clearances, adequate ventilation for KT-13 nonlinear ventilation, and compliance with NEMA TP-1 guidelines. Outdoor or harsh environments should utilize WS19 weather shield. Finally, verify UL Listed certification and maintain the one-year warranty terms.
The K-Factor nonlinear ventilation manages harmonic and transient loads more effectively, reducing hot spots and improving overall efficiency under non-ideal power conditions. This design supports higher temperature rise tolerance (150 °C rise) while maintaining insulation integrity (200 °C insulation system). The result is improved uptime, longer transformer life, and lower cooling costs in variable automation environments.
Yes. With 75 kVA rating, 380 V primary, 208Y/120 V secondary, and precise tapping, it accommodates critical automation loads while providing reliable voltage regulation. UL Listed and NEMA TP-1 compliant, it meets industry safety and efficiency standards. The copper windings and weather-shielded configuration also support reliability in data center and manufacturing deployments with demanding operating conditions.
This unit is UL Listed and NEMA TP-1 Compliant, with NEMA TP-1 efficient catalog notes. UL Listing confirms safety and material compliance, while NEMA TP-1 compliance and efficiency designation support regulatory and energy-performance requirements in industrial installations. Together, they reduce risk and simplify procurement for regulated facilities.
The warranty is one year from installation or eighteen months from shipment, whichever occurs first. Regular maintenance and thermal management reduce the likelihood of premature failures. The combination of robust construction, copper windings, and effective cooling translates to lower lifecycle costs, less downtime, and a favorable return on investment for large-scale automation projects.
