Reliance 86466-60R Rectifier Stack Assembly

Reliance 86466-60R Rectifier Stack Assembly is a two-heat-sink gate rectifier stack built on a hollow metal carrier designed for mounting in legacy drive systems. The unit uses two 2‑section heat sinks, each topped with a gate-coupling PCB labeled 0-51378-19, and is secured to the carrier by three mounting brackets. The gate‑coupling boards house three resistors, three diodes, a transformer, and four pins that connect to the heat sinks, forming the gate-drive and rectification network central to the stack's operation. This part sits in the Reliance/Reliance Electric lineage (also associated with Baldor Reliance and ASEA Brown Boveri) as a rectifier stack module; it is documented by distributors as a "rectifier stack" or "gate rectifier stack" and is noted as discontinued/rare in current inventories.
