Allen-Bradley 193S-EERB Single Phase Overload Relay

Allen-Bradley 193S-EERB is a solid-state, single-phase overload relay from the E1 Plus family that provides 3.2–16 A overload protection for AC motors. It is designed for use with Allen-Bradley 100-C series contactors (frames 100-C09 through 100-C23) and mounts on a panel or DIN rail with pass-thru wiring for streamlined wiring. The unit offers selectable trip class settings of 10, 15, 20, or 30 and supports Auto/Manual Auto Reset operation, allowing either automatic protection cycling or a manual reset workflow. As a 1-phase overload relay, the 193S-EERB pairs with motor control circuits in industrial equipment, conveyors, fans, and machine tools, delivering precise current sensing and protection in startup and running conditions. This model is the single-phase variant in the 193S-EER family, with a maximum controllable current in the 3.2–16 A range, ensuring compatibility with small to mid-size motors in standard industrial applications.
