Totally enclosed non-ventilated (dry-type) design protects windings and joints from dust and moisture, reducing maintenance cycles and extending service life in indoor switchgear rooms. Business impact: higher uptime and lower cooling requirements translate to smaller equipment rooms and lower operating costs. Application: ideal for factory floors, control rooms, and panel boards where cleanliness and space are critical. Copper windings deliver superior conductivity and durability, improving efficiency and voltage regulation under load. Business impact: lower I2R losses and stable output for sensitive automation equipment. Application: drives, PLCs, and motor starters in production lines. Tap settings of 2 at +2.5% and 4 at -2.5% enable precise voltage regulation, minimizing nuisance trips and protecting connected loads. Business impact: improved voltage stability and reduced equipment wear. Application: facilities with variable loads and startup surges. Frame 923N and a footprint of 32.65 in L x 32.02 in H x 36.6 in W support plug-and-play installation with standard clearances. Business impact: faster commissioning and scalable deployment. Temperature rise of 115°C ensures robust performance in moderate ambient conditions, sustaining reliability through peak demand. Application: environments with fluctuating temperatures and continuous operation. Certifications include UL Listed, signaling compliance with essential electrical safety standards for industrial power distribution.

FAQs
Verify the transformer's primary voltage rating (480 V) matches your incoming supply and confirm your system operates at 60 Hz. Check the secondary voltage (208Y/120 V) aligns with downstream loads. Review the device's DT-3 dry-type design for indoor distribution, and ensure space, clearance, and cooling provisions meet installation standards.
No external cooling fan is required due to the totally enclosed non-ventilated enclosure, reducing maintenance tasks. Regular visual inspections, insulation checks, and periodic thermal monitoring are advised. Ensure enclosure integrity to prevent dust ingress, maintain proper clearances, and verify tap settings remain within specification during routine service.
Yes. The 208Y/120 V secondary is designed for control panels, automation equipment, and machine room feeders. The copper windings and DT-3 design support efficient energy transfer and voltage stability, helping to protect sensitive electronics and improve startup reliability for motors and drives.
The unit carries UL Listed certification, validating electrical safety and reliability for indoor power distribution. Confirm any site-specific compliance requirements, local electrical codes, and adherence to manufacturer installation instructions, including enclosure integrity and acceptable ambient temperature ranges for continuous operation.
Expect a favorable total cost of ownership due to reduced cooling needs from a dry-type, non-ventilated design, lowered maintenance burden, and improved reliability from copper windings and robust enclosure. Together, these factors minimize downtime, extend service intervals, and stabilize voltage to critical loads, delivering lower lifecycle costs in industrial facilities.
