Reliance Electric 86466-58R Rectifier Stack Assembly

Reliance Electric 86466-58R Rectifier Stack Assembly is a multi-diode rectifier module used in older Baldor Reliance drive systems to convert AC input to DC for motor control within industrial power modules. Also cataloged as O-86466-58R, it sits in the ASEA Brown Boveri Baldor Reliance lineage, reflecting cross-brand compatibility. The assembly carries secondary identifiers such as 608881-31 and is recognized in supplier catalogs as 8646658R. Available from distributors as new or reconditioned stock, it is commonly used in repair or refurbishment projects for legacy equipment. In listings, buyers sometimes encounter the 0-51378-25 gate coupling board referenced alongside the 86466-58R, indicating common integration with gate drive components in compatible drive architectures. This rectifier stack is typically deployed in legacy DC drive configurations and motor-control power modules within industrial settings, where reliable rectification hardware from the Reliance/Baldor family is required to maintain operational equipment.
