Resin-encapsulated copper windings provide superior moisture and dust resistance, reducing insulation degradation and unplanned downtime. This translates into longer service life and lower maintenance costs in hazardous locations. Use in control rooms and power distribution in chemical plants, offshore platforms, and other Class I Division 2 environments. Three-phase operation at 60 Hz with a 150 kVA rating ensures consistent, balanced power delivery from 600 Vac to 208Y/120 Vac. This enables safe, reliable feeding of control circuits and motors in hazardous zones, improving uptime and reducing voltage-related equipment stress. 600 Vac primary and 208Y/120 Vac secondary voltages enable direct powering of feeders and local instrumentation, minimizing the need for additional step-down equipment and simplifying installation. Rugged painted steel enclosure rated for NEMA 4 and approved for Class I Division 2 locations delivers durable performance in outdoor, washdown, or harsh indoor environments. UL certifications and NEC/CEC compliance documentation support fast regulatory approvals and safer commissioning. With a footprint of 36.63 in length, 31.38 in height, and 30.5 in width and a weight of 2677 lb, the XTT3D150 is purpose-built for factory and plant-scale deployments, and is compatible with standard rigid-bus and switchgear connections, enabling straightforward integration into existing power systems.

FAQs
The XTT3D150 is a 150 kVA, three-phase dry-type transformer designed for Class I Division 2 environments. It converts 600 Vac to 208Y/120 Vac for control panels, motors, and instrumentation, delivering reliable power in chemical plants, offshore facilities, and other hazardous locations while meeting NEC/CEC standards.
The transformer features a 600 Vac primary voltage and a 208Y/120 Vac secondary voltage. This configuration supports direct feeding of 120/208 V load centers and equipment in hazardous environments, reducing the need for additional step-down gear and simplifying installation.
Yes. The XTT3D150 is designed for NEC/CEC compliance with NEC hazardous location Class I Division 2 protection. It also features a NEMA 4 enclosure suitable for harsh outdoor and washdown conditions, aligning with robust regulatory and environmental requirements.
Resin encapsulation seals copper windings against moisture, dust, and contaminants, reducing insulation degradation and corrosion risk. This lowers maintenance frequency, minimizes downtime, and extends service life in challenging environments such as chemical plants and offshore facilities.
The XTT3D150 has a footprint of 36.63 in L Ă— 30.5 in W Ă— 31.38 in H and weighs 2677 lb, requiring crane-assisted placement and a solid, level foundation. Its three-phase 600 Vac input and 208Y/120 Vac output simplify mounting to standard switchgear or panel boards, streamlining integration into existing power systems.
