Description
Low Voltage General Purpose Dry-Type Transformer
ABB Low Voltage General Purpose Dry-Type Transformers are three-phase ventilated transformers designed for dependable commercial, industrial, and general-purpose electrical distribution applications. These models convert a 480-volt primary supply to a 208Y/120-volt secondary and are available in ratings from 30 kVA through 150 kVA.
The transformer family features aluminum windings, a 150°C temperature rise, NEMA 2 enclosure construction, 60 Hz operation, and DOE 2016 energy-efficiency performance. Core and coil assemblies are mounted on rubber isolation pads to help reduce operating noise, while removable front and back sections help simplify installation and service access.

Construction Details
ABB Low Voltage General Purpose Dry-Type Transformers use a ventilated dry-type construction intended for reliable electrical distribution without the use of liquid dielectric cooling.
These models use aluminum windings and are designed with a 150°C temperature rise. Core and coil assemblies are mounted on rubber isolation pads to help minimize the transmission of transformer operating noise.
A removable single-piece front and back construction provides convenient access during installation and future electrical service work. The transformers are housed in NEMA 2 enclosures for compatible indoor general-purpose applications.
