Allen-Bradley 193-EA1DB Overload Relay

Allen-Bradley 193-EA1DB is a solid-state overload relay (Bulletin 193) that provides electronic motor protection for AC motors in light- to mid-duty applications. With a current sensing range of 1.0 to 2.9 A and a manual reset, it requires a deliberate acknowledgment before restart after a fault. This model is designed for use with Allen-Bradley Bulletin 100-M05 through 100-C23 contactors, enabling integrated overload protection in standard starter assemblies. As part of the 193 family, the EA1DB delivers Class 10 trip performance, helping prevent motor damage from overcurrent by opening the circuit when the preset current is exceeded. Typical applications include conveyors, pumps, fans, and machine tools where compact protection and straightforward reset are desired. The relay is intended to accompany compatible Allen-Bradley contactors in control panels, forming a compact protective trio with the contactor for reliable motor protection. When selecting replacements or verifying compatibility, confirm the current rating and wiring with the existing 100-M05…100-C23 assembly.
