Allen-Bradley 193-EA2FB Overload Relay 3.7-12A

Allen-Bradley 193-EA2FB is a solid-state overload relay in the Series B family that mounts directly to compatible Allen-Bradley contactors to protect three‑phase motors from overload. It provides an adjustable current range of 3.7 to 12 A and is specified as a Class 20 overload device, designed to trip on sustained overcurrent to safeguard motor windings and drive circuitry. This model is the manual-reset variant, requiring operator action to reset after a fault before restart. The 193-EA2FB is designed for use with select 100-series and M-series contactors, including 100-C09, C12, C16, C23 and M05, M09 line models, and it supports direct mounting to compatible contactors such as the 100-M9 in certain configurations.
