Overview
The Allen-Bradley 193-EA1EB is a solid state overload relay designed for motor protection in industrial control systems. This Class 10 relay provides reliable overload detection and trip response, with manual reset capability. The 193-EA1EB operates at 690 VAC and handles motor full-load amperage from 1.6 to 5.0 amps, making it suitable for small to medium motor circuits. Though discontinued by the manufacturer, the 193-EA1EB remains a dependable component for legacy equipment maintenance and retrofit applications.
