Allen-Bradley 193-TAB40 A is a thermal overload relay from the 193‑T family used to protect motors by opening the circuit when overload current is detected. It is designed for use with Allen-Bradley Bulletin 100-C contactors and features ambient-temperature compensation to maintain consistent trip characteristics across a wide operating range, typically from -20 °C to +60 °C. The A40 designation identifies its current-range configuration within the 193‑T series, making it suitable for small-motor protection in industrial automation environments.
