Understanding the Code:

“ABB UNITROL 1020” likely refers to the ABB UNITROL 1000 series, a product line of automatic voltage regulators.
“3BHE030579R0003” might be a specific revision, serial number, or variant code within the UNITROL 1020 series.
Finding Information:

Prioritize Verified Information (Most Reliable):

Contact ABB Technical Support: This remains the most trustworthy approach. ABB might have archived information on older products like the UNITROL 1020.

When contacting ABB, provide the complete code “ABB UNITROL 1020+3BHE030579R0003”.
Inquire about:
Product Name: Official name associated with the code, mentioning the “+” symbol.
Description: Function of the module within a system (e.g., excitation system component, converter module).
Parameters and Specifications: Ask for details on voltage rating, current rating, communication protocols (if applicable), and any relevant performance specifications.

The UNITROL 1020 might be an older product line. Finding detailed information, especially regarding the “+” symbol’s meaning, could be challenging, but ABB might have archived resources.
Use online resources cautiously, prioritizing verified information from ABB.
Additional Notes:

If you have access to older manuals or documentation for the system where the UNITROL 1020 3BHE030579R0003 module is used, those resources might be most relevant for understanding its function and specifications within that specific setup.
