General Purpose Isolation Transformer

General Purpose Isolation transformers

General Purpose Isolation transformers are used to lower distribution voltages (480 or 600V) to lower voltages (typically 120/240 or 208Y120) for power distribution within commercial or industrial buildings. These “two windings” transformers provide the electrical isolation required, and allow for short runs of high current, low voltage cables, reducing losses in the system, and reducing costs. 

General Purpose Isolation transformer are suitable for supplying the following type of loads

• General purpose lighting & electrical
• Motors (without VFD controllers)
• Resistive Heating

Features and Benefits
