Information About 3F3Y075ST
The 3F3Y075ST is part of Siemens’ dry-type transformer line, designed to provide safe and efficient step-down power conversion for 3-phase systems. With a 75 kVA rating, it is capable of handling medium-to-large scale loads in commercial buildings, industrial plants, and institutional facilities. The transformer reduces incoming 480 V power to 120/208 V, making it suitable for distribution to standard low-voltage systems. Housed in a NEMA 1 rated enclosure, the unit is built for indoor installations where protection against dust and incidental contact is required. Its air-cooled, dry-type design minimizes maintenance needs while ensuring long service life.
Key Features:
-
75 kVA Rating: Delivers reliable power capacity for commercial and industrial applications.
-
3-Phase Transformer: Designed for balanced and efficient three-phase power distribution.
-
Step-Down Conversion: Converts 480 V high voltage to 120/208 V low voltage for downstream systems.
-
Dry-Type Cooling: Air-cooled construction reduces maintenance requirements and eliminates oil handling.
-
Indoor Enclosure: NEMA 1 housing ensures safe use in protected indoor environments.
-
Durable Siemens Build: Engineered for long service life and consistent performance.
-
UL Listed Compliance: Meets recognized safety and performance standards.
-
Versatile Applications: Supports commercial buildings, industrial operations, and institutional power needs.
The 3F3Y075ST delivers the reliability and precision required for safe, efficient step-down power distribution in 3-phase systems.
