Westinghouse A203J1AZAC Fusible Starter Combo

The Westinghouse A203J1AZAC Fusible Starter Combo is a Size 1, three-phase magnetic fusible starter that combines motor starting, overload protection, and fused disconnect in a single enclosure for industrial motor control. It uses a 115/120 V coil and supports 50/60 Hz operation with a 3-pole configuration, enabling reliable power switching and circuit protection in motor circuits. Designed for mounting in enclosures or panels, this industrial-grade electromechanical assembly integrates starting and protection functions to support machinery and process equipment in manufacturing facilities. Typical applications include manufacturing equipment, conveyors, pumps, HVAC systems, compressors, and material handling equipment, as well as industrial motor control centers where stable starting, short-circuit protection, and fused isolation are critical for uptime and safety. The starter is used in motor control and automation systems for upgrades, replacements, and ongoing electrical maintenance to ensure dependable operation across industrial automation panels. Common replacements include Allen-Bradley Bulletin 509 Combination Starter, Siemens SIRIUS Fusible Motor Starter, and Eaton Freedom Combination Motor Starter.
