The SolaHD HT1F15AS is a 15 kVA three-phase encapsulated automation transformer designed for industrial applications. It features a primary voltage of 480 VAC and a secondary output of 208Y/120 VAC, operating at a frequency of 60 Hz. The unit is housed in a NEMA Type 3R enclosure, providing protection against dust and moisture while offering resistance to shock and vibration. Rated for Class I, Division 2 hazardous locations, it complies with the National Electrical Code when installed correctly.
Verify that the specific order matches the HT1F15AS part number, which denotes a 15 kVA, 480V primary to 208Y/120V secondary configuration. Confirm that the NEMA 3R enclosure rating aligns with the required environmental protection standards for the installation site. Ensure compliance with NEC Class I, Division 2 requirements for any hazardous location deployment.
Select this model when a robust, encapsulated three-phase transformer is required for automation or OEM applications. The choice is driven by the need for high durability in harsh environments, specifically where dust and moisture resistance are critical. The 15 kVA capacity and specific voltage transformation ratio must match the load requirements of the target industrial machinery.
This component belongs to the SolaHD HT1 series of encapsulated automation transformers. These units are engineered for reliability in demanding settings, combining rugged construction with electrical safety certifications. The series is widely used in industrial control and automation sectors where standard ventilation-based transformers may fail due to environmental contaminants.
When replacing existing units, ensure the new transformer matches the 15 kVA rating and the 480V to 208Y/120V voltage configuration. Verify that the replacement also meets NEMA 3R enclosure standards and holds UL listing for Class I, Division 2 locations to maintain system safety and code compliance.
