FAQs
Plan for a stable floor mount to support the 388 lb weight and ensure adequate ventilation around the 20.36 in depth, 37.59 in height, and 22.89 in width footprint. Verify enclosure clearance for servicing, allow space for the WS11 weather shield, and follow installer guidelines to accommodate the aluminum coil and frame 818 construction.
It is a single-phase, 22.5 kVA transformer operating at 60 Hz with 208 V primary and secondary. It features taps at +2.5% and -2.5%, aluminum coil windings, a 150 °C rise rating, and is designed for 208 V distribution in panel boards and control installations.
Yes. Its K-Factor nonlinear ventilation, precise taps, and 22.5 kVA rating support stable voltage for controls and drives. The aluminum coil and robust frame provide mechanical resilience, while UL Listed and NEMA TP-1 efficiency help ensure reliable performance in busy manufacturing environments.
This transformer is UL Listed and NEMA TP-1 compliant and efficient. These certifications reduce procurement risk, simplify regulatory audits, and confirm energy-performance expectations, making it easier to pass compliance checks for industrial power distribution installations.
By improving voltage stability and reducing heat buildup, it lowers downtime and extends component life in control panels and substations. The built-in protections, weather shielding, and compliance certifications also lower maintenance costs and simplify future upgrades, contributing to a lower total cost of ownership over the equipment’s life cycle.
