HT3F6AS

Overview

The SolaHD HT3F6AS is a 6 kVA three-phase encapsulated automation transformer designed for rugged industrial environments. It features a rolled steel construction with a 208V Delta primary and a 208Y/120V secondary configuration. The unit provides 14.4A primary current and 16.6A secondary current capacity. Rated for NEMA 3R enclosure protection, it operates without ventilation requirements, ensuring dependable voltage transformation in hazardous locations such as Class 1, Division 2 areas.

Feature Summary

• Encapsulated design for environmental protection in hazardous locations
• Non-ventilated operation suitable for confined or dusty industrial settings
• Rolled steel construction for mechanical durability
• NEMA 3R enclosure rating for outdoor or washdown resistance

Applications

• Industrial machinery requiring stable three-phase power conversion
• Automation equipment in hazardous location zones
• OEM systems needing compact, encapsulated voltage transformation
• Control circuits deriving 120V from 208V three-phase sources

Procurement Notes

Verify the specific voltage configuration (208D-208Y) matches your system requirements before ordering. Confirm that the NEMA 3R enclosure rating satisfies your environmental protection needs. Ensure the 6 kVA capacity aligns with your load calculations. Check for any specific hazardous location certifications required by local regulations. Validate physical dimensions and mounting style against your installation space constraints.

Selection Notes

Select this model when a non-ventilated, encapsulated transformer is required for harsh environments. Consider the 208V Delta to 208Y/120V step-down ratio for control power applications. Evaluate the 6 kVA rating against peak and continuous load demands. Ensure compatibility with existing three-phase infrastructure. Verify that the chassis mount style fits your panel or rack layout.

Part Context

This component belongs to the SolaHD HT series of non-ventilated automation transformers. The series ranges from 50 VA to 45 kVA, offering various voltage configurations and enclosure options. These transformers are engineered for Emerson's SolaHD brand, focusing on reliability in industrial automation and hazardous area applications.

Replacement Considerations

Direct substitutes may include other SolaHD HT series models with matching kVA ratings and voltage configurations. Verify that alternative parts maintain the same encapsulation type and NEMA 3R rating. Ensure physical footprint and mounting hole patterns are compatible. Confirm that the replacement meets the same hazardous location classification standards.
