Allen-Bradley 193-EA2AB Overload Relay Class 20

The Allen-Bradley 193-EA2AB Overload Relay provides thermal overload protection for small three-phase and single-phase motors within motor control systems, safeguarding equipment in motor starters, conveyors, pumps, fans, compressors, and other industrial machinery. As part of Bulletin 193, this Class 20 relay is a bimetallic overload device with an adjustable current range of 0.10–0.32 A, enabling precise protection for a variety of motor sizes, and it offers either manual or automatic reset to suit maintenance workflows. Integrated trip contacts give clear fault indication, and the relay supports direct contactor mounting or standalone installation for flexible integration into existing panels. The 193-EA2AB is designed for IEC motor protection standards and is suitable for both single-phase and three-phase motors, making it a common choice in motor starter protection, packaging equipment, material handling systems, HVAC equipment, and general industrial automation where reliable overload protection is essential. Maintenance teams and system integrators rely on this Allen-Bradley part for replacements, retrofit projects, and motor control panel upgrades to protect motors from overload conditions and extend equipment service life.
