Selling Policy 25-000 - Distribution and Control Products and Services
Harmonic mitigation is engineered into the core design, reducing THD and smoothing voltage waveforms for sensitive loads. The result is lower transformer heating, improved efficiency, and extended equipment life in critical applications. This makes it ideal for data centers, PV inverters, and high-demand manufacturing lines where power quality directly affects uptime. The transformer offers taps at +2.5% and -2.5% to compensate voltage drop along feeders and during loading transients, translating to tighter voltage regulation at the load end and reducing nuisance trips. It’s particularly valuable in facilities with long distribution runs or varying supply quality. Copper windings and an 80°C rise rating indicate robust construction and thermal performance, delivering dependable operation in challenging environments. The dry-type insulation facilitates safer installation in occupied spaces and supports conservative maintenance planning. Two embedded thermal indicators enable quick visual checks, supporting proactive maintenance and minimized outages. The 150 kVA rating complements this by enabling scalable load growth without equipment replacement. Compliance and protection features include UL Listed certification, NEMA TP-1 efficiency considerations, and a WeatherShield option WS34 for outdoor installations. These attributes reduce regulatory risk and simplify project compliance. Easy integration is aided by a 203X wiring connection and a standard footprint, easing field installation and future upgrades. Dimensions (approximate) and weight inform mounting decisions for concrete pads or enclosures in constrained spaces.

FAQs
Plan for a three-phase, 480 V feed using the 203X wiring connection. Verify clearances and mounting accommodating the unit’s dimensions (30.68 in L x 62.18 in H x 31.44 in W) and weight (≈2325 lb). Use the WS34 weather shield option for outdoor or exposed installations. Incorporate the +2.5% and -2.5% taps to stabilize feeder voltage during load changes and perform routine thermal monitoring via embedded indicators.
The transformer is rated 150 kVA with a 480 V primary and a 400Y/231 V secondary. It operates at 60 Hz in a three-phase configuration with a phase shift of -30 degrees. It uses copper windings and has an 80°C rise rating. It’s UL Listed and NEMA TP-1 compliant, designed for efficient, reliable operation in demanding environments.
Yes. Its harmonic mitigation reduces THD, improving power quality for sensitive electronics in data centers and PV inverters, while the robust copper windings and strict compliance support continuous manufacturing operations. The adjustable taps help maintain stable voltage, minimizing downtime and equipment wear.
Two primary considerations are UL Listed certification for safety and NEMA TP-1 efficiency compliance. The unit also holds a NEMA TP-1 efficient design, with dual embedded thermal indicators for ongoing monitoring. For outdoor deployments, WS34 WeatherShield enhances protection against environmental factors.
