Overview
The SolaHD HTP81F9AS is a 9 kVA three-phase encapsulated automation transformer. It features a 480 Delta primary and a 480Y/277 VAC secondary winding configuration. The unit operates at 60 Hz and is rated for NEMA Type 3R environmental protection. This non-ventilated, chassis-mount device is UL Listed and designed for hazardous locations.
Feature Summary
- Encapsulated construction for hazardous location suitability
- NEMA Type 3R rating for outdoor or harsh environments
- Non-ventilated design for compact chassis mounting
Applications
- Industrial automation systems requiring phase conversion or voltage transformation
- Hazardous location power distribution
- Harsh industrial environment control circuits
Procurement Notes
Verify the specific part number suffix against official Emerson/SolaHD documentation to confirm electrical ratings and enclosure type. Ensure the procurement specification matches the required 480V delta primary and 480Y/277V secondary configuration. Confirm NEMA Type 3R compliance if outdoor exposure is anticipated.
Selection Notes
Select this model when a 9 kVA capacity is required for three-phase applications with a 480V input and 480Y/277V output. Consider the encapsulated, non-ventilated design for environments where dust or moisture ingress must be prevented without active cooling. Verify hazardous location classification requirements before installation.
Part Context
This component belongs to the SolaHD Automation Transformers series by Emerson Electric Co. The HTP81 series includes encapsulated units ranging from 50 VA to 45 kVA. These transformers are engineered for durability in demanding industrial settings, offering robust protection against environmental factors through their sealed construction.
Replacement Considerations
Consult official SolaHD cross-reference guides for direct replacements. Ensure substitute models match the 9 kVA rating, 480D/480Y/277V configuration, and NEMA Type 3R rating. Verify hazardous location approvals for any alternative components.
