SolaHD Floor Mount Automation Transformers provide reliable voltage transformation and electrical isolation for larger industrial automation and power distribution applications. Their non-ventilated, encapsulated construction helps protect the transformer from dust, moisture, shock and vibration in demanding operating environments.
The series includes three-phase transformers from 15 kVA through 150 kVA. Standard catalog configurations include 480 volt delta primary models with either 208Y/120 volt or 480Y/277 volt secondary outputs, providing common voltage combinations for industrial machinery, automation systems, control equipment and facility distribution.
These transformers are electrostatically shielded for quality power and use a UL Class 200°C insulation system with a 115°C temperature rise at a 40°C ambient temperature. Copper terminations and removable gland plates help simplify cable entry, installation, rewiring and future equipment relocation.
The official SolaHD datasheet includes complete catalog-number tables, kVA ratings, primary and secondary voltages, dimensions, shipping weights, amperage information, enclosure details, gland-plate accessories and electrical connection diagrams.

SolaHD Floor Mount Automation Transformers are designed for industrial installations where larger transformer capacity and rugged environmental protection are required. Their encapsulated, non-ventilated construction makes them suitable for applications exposed to dust, moisture, shock or vibration where a standard ventilated transformer may not provide the necessary protection.
The standard series includes three-phase ratings of 15, 30, 45, 75, 112.5 and 150 kVA. Available standard voltage configurations include:
Both standard configurations include primary voltage taps for 492, 480 and 468 volt input conditions. The required output voltage, connected load and available source voltage should be confirmed before selecting a catalog number.
Standard models are offered in ANSI gray painted cold-rolled steel enclosures suitable for NEMA Type 1, 2, 3R, 4 and 12 applications. NEMA 4X stainless-steel enclosure configurations are also available for installations requiring increased corrosion resistance.
The enclosure and certification must match the actual installation environment. Confirm exposure to moisture, dust, washdown, corrosive materials, ambient temperature and hazardous gases or vapors before selecting the final model.
Applicable models are cULus Listed for Class I, Division 2/Zone 2 hazardous locations with T3C or T3 temperature classifications. These ratings can make the series suitable for industrial areas where flammable gases or vapors may be present under abnormal operating conditions.
Hazardous-location suitability depends on the exact model, temperature classification, installation method and applicable electrical code requirements. Always verify the individual transformer certification before ordering or installation.
Begin by confirming the available three-phase primary voltage and the required secondary voltage. Then calculate the connected-load requirement and select a transformer with a nameplate kVA rating equal to or greater than the load.
For a three-phase load, transformer capacity can be calculated using:
kVA = Volts × Amps × 1.732 ÷ 1,000
Available options include NEMA 4X stainless-steel enclosures, designs for 50°C ambient temperatures, alternate hazardous-location temperature classifications, copper-wound configurations, K-factor designs and low-temperature-rise designs.
Replacement gland plates are also available for moves, additions and equipment rework. The standard replacement gland plate is selected according to the transformer kVA range.
Applicable models are listed under UL file E361435 and comply with UL 1561 or UL 5085-1 and UL 5085-2, CSA C22.2 No. 47 or No. 66, and RoHS requirements.
Certifications, enclosure ratings and temperature classifications should always be confirmed for the individual catalog number before purchase or installation.
For help selecting a SolaHD Floor Mount Automation Transformer, provide Wallco with the available primary voltage, required secondary voltage, connected load, ambient temperature, enclosure requirement and hazardous-location classification.
