HT1F3AS

Overview

The SolaHD HT1F3AS is a 3 kVA encapsulated automation transformer designed for industrial control applications. It features a laminated core and chassis mount configuration. The unit operates at 60 Hz with NEMA Type 3R enclosure rating, providing protection against dust and moisture. Electrical specifications include a 480V Delta primary and 208Y/120 VAC secondary output. It supports UL 506, UL 1561, and CSA C22.2 approvals, ensuring compliance with safety standards for harsh environments.

Feature Summary

• Encapsulated construction provides rugged protection against dust, moisture, shock, and vibration in harsh industrial settings.
• NEMA Type 3R enclosure ensures durability and suitability for hazardous location ratings.
• Laminated core design supports efficient power transformation for industrial control systems.

Applications

• Industrial control panel power distribution
• Automation equipment voltage step-down
• Harsh environment machinery power supply

Procurement Notes

Verify the specific electrical configuration required for your application, as sources indicate conflicting primary voltage options (480V Delta vs. 120/208/240/277V). Confirm phase requirements, as some listings describe it as three-phase while others specify single-phase. Ensure the NEMA Type 3R enclosure meets environmental protection needs. Cross-reference UL and CSA approval markings on the physical unit to match regulatory requirements.

Selection Notes

Select this model when a 3 kVA capacity is needed for industrial automation. The encapsulated design is critical for environments requiring resistance to moisture and particulate ingress. Verify that the 480V Delta primary matches the available supply voltage. Consider the chassis mount style for integration into existing control panels. Ensure the 208Y/120V secondary output aligns with downstream control circuit requirements.

Part Context

The HT1F3AS belongs to the SolaHD HT Series of encapsulated transformers. This series is engineered for reliability in demanding industrial conditions. The product line emphasizes durability through non-ventilated encapsulation techniques. It serves as a robust solution for stepping down voltages in automated manufacturing and processing facilities where standard transformers might fail due to environmental factors.

Replacement Considerations

Direct substitutes must match the 3 kVA rating, 60 Hz frequency, and NEMA Type 3R enclosure. Verify primary voltage compatibility (480V Delta) and secondary output (208Y/120V). Check mounting dimensions and terminal configurations for mechanical fit. Ensure equivalent UL and CSA certifications are maintained for code compliance in hazardous locations.
