Reliance Electric 86466-92SB Rectifier

Reliance Electric 86466-92SB Rectifier is a rectifier stack assembly intended for inclusion in DC power modules within industrial drives and power-conversion equipment. The unit is configured as a rectifier stack with a two-bracket mounting arrangement and dual heat sink stacks, enabling compact cooling in enclosed installations. The 86466-92SB designation is sometimes cataloged as 8646692SB in listings and reflects the long-running Reliance Electric/ABB/Baldor lineage of motor drive components. In distributor and resale catalogs, it is described as a rectifier stack and is noted as discontinued by the manufacturer, meaning stock is generally found only in secondary markets or surplus channels. The assemblies in this family are associated with Reliance Electric's DC power module offerings and appear alongside other 86466-series rectifier stacks and thyristor/rectifier assemblies used in vintage drive systems.
