Reliance 410403-38AW Thyristor

Reliance 410403-38AW Thyristor is a high-current silicon-controlled rectifier (SCR) module in Rockwell Automation’s Reliance Electric lineage. The device is rated for 500 A forward current and 1,200 V peak reverse voltage (PRV), enabling it to handle demanding power-switching tasks in industrial power electronics. Identified by the 410403-38AW part number, this thyristor module sits in Rockwell’s catalog of power semiconductors used in automation and drive systems. As a standalone thyristor element designed for high-current switching, it supports SCR-based circuits in industrial equipment that require robust, line-commuted control for switching heavy loads. The combination of a 500 A rating and 1.2 kV PRV provides reliable operation under peak-load conditions in power-regulating assemblies and drive modules that rely on solid-state switching. The part is associated with the Reliance Electric/Rockwell family of power semiconductors and is referenced in multiple catalog and distributor listings under the 410403-38AW designation.
