Square D 30T3HFISNL Distribution Transformer

Square D 30T3HFISNL is a 30 kVA dry-type distribution transformer that steps 480 V three-phase power down to 208Y/120 V, providing reliable 120/208 V service for facilities loads such as lighting and equipment in commercial and industrial settings. This energy‑efficient unit aligns with DOE 2016 standards for low‑voltage transformers and operates at 60 Hz, making it suitable for indoor installation in electrical rooms, panels, and switchgear configurations. The HFISNL suffix identifies a specific enclosure/configuration variant within Square D’s 30 kVA family, maintaining a 480 V delta primary and 208Y/120 V secondary rating across the line for compatibility with Square D equipment and standard distribution layouts. Designed to support critical loads in applications like data centers, manufacturing, and facilities infrastructure, this transformer delivers three‑phase power conversion with predictable performance and proven Square D reliability.
