Reliance Electric 86471-S Rectifier Stack Assembly

The Reliance Electric 86471-S Rectifier Stack Assembly is a dedicated rectifier stack identified by part number 86471-S (86471S) that is designed for use with Reliance Electric medium‑voltage controller modules. This assembly consolidates the rectifier components into a single replaceable unit intended to provide DC output for compatible industrial control systems in drive and power‑electronics applications. The 86471‑S designation appears in multiple spare‑parts catalogs and distributor listings as the stack component required when a controller specifies the 86471‑S family, indicating its role within the controller architecture rather than as a standalone power module. When equipment documentation references 86471-S, this rectifier stack corresponds to the stack assembly described by the controller manuals and cross‑references in those catalogs. To ensure proper fit and electrical compatibility, consult the exact controller model and any required wiring harness or accessory interfaces in Reliance Electric or authorized distributor documentation before purchasing. In practice, replacement stacks like the 86471-S are commonly sourced from specialized industrial‑electronics suppliers that maintain legacy Reliance Electric components for service and retrofit projects.
