The SolaHD HT5F45AS is a non-ventilated, encapsulated three-phase automation transformer with a 45 kVA power rating. It operates at a frequency of 60 Hz and features a 480 VAC delta primary voltage connected to a 240Y/120 VAC secondary configuration. Designed for industrial environments, this unit meets UL, CUL, and CSA safety approvals and complies with NEC 501-2(B) standards for hazardous locations. The physical dimensions are 25 inches in width, 12 inches in depth, and 30 inches in height.
Verify that the specific application environment aligns with the NEC 501-2(B) hazardous location classification. Confirm that the electrical load does not exceed the 45 kVA rating and that the 480V delta to 240Y/120V conversion matches the system requirements. Ensure physical clearance accommodates the specified 25x12x30 inch footprint.
Select this model when a three-phase step-down transformation from 480V to 240/120V is required in a hazardous area. The encapsulated, non-ventilated design eliminates the need for external cooling fans, making it suitable for sealed enclosures where dust or explosive atmospheres are present.
This component belongs to the SolaHD Sola/Hevi-Duty Automation Transformers series. It is part of a product line offering non-ventilated encapsulated transformers ranging from 50 VA to 45 kVA, specifically engineered for demanding industrial control applications requiring robust environmental protection.
