Reliance Electric Company 701819-302AW Thyristor

Reliance Electric 701819-302AW Thyristor is a silicon-controlled rectifier (SCR) device from the Reliance Electric family, a lineage that has included Baldor Reliance and Allen-Bradley–branded components through corporate transitions. The 701819-302AW designation identifies a specific thyristor module used in industrial power‑electronics assemblies, and it is commonly listed by distributors as a replacement part for legacy Baldor/Reliance equipment. As a thyristor, it is triggered by a gate signal to begin conducting current and will continue to conduct until the current falls below its holding value, enabling controlled rectification and switching in power conversion stages. This part appears in catalogs and distributor listings associated with mid‑ to large‑scale industrial drive and power‑control systems, reflecting its role in industrial electrical infrastructure. Because this is a historic component with a brand heritage spanning Reliance Electric, Baldor, and ABB, be sure to obtain the exact electrical ratings, mounting footprint, and packaging details from the supplier’s datasheet before purchasing or integrating it into equipment.
