FAQs
The CV24M47T45EE is designed for use in standard 3-phase panels with a 240 V primary and 480Y/277 V secondary. Mount the transformer on a stable base, connect the primary to the local 240 V supply, and wire the secondary outputs to the downstream control circuits, ensuring correct phase alignment. Use proper torque on terminal lugs, verify taps are set for operating voltage, and follow local electrical codes during commissioning.
Key specs include a 45 kVA VA rating, 240 V primary, 480Y/277 V secondary, 60 Hz frequency, and taps at +2.5% / -2.5%. The transformer features a 150 °C temperature rise and a 200 °C insulation system, with a 912D frame. These factors influence load capacity, thermal performance, and long-term reliability in your distribution design.
Yes. With 3-phase 45 kVA capability, compatible secondary voltages, and a rugged NEMA 2 enclosure, the CV24M47T45EE fits automation panels and manufacturing environments. The voltage regulation provided by the taps helps maintain stable control signals for PLCs and drives, reducing nuisance faults and improving process consistency.
This transformer is CSA Certified and UL Listed, indicating compliance with safety and performance standards for electrical equipment in North America. These certifications reduce risk in audits and installations, support warranty validity, and simplify procurement when meeting regulatory requirements for industrial facilities.
