Siemens SA13A Thermal Overload Relay is a motor-protection device designed for use with Siemens SXLBO starters, configured for Size 0. It functions as a thermal overload relay within the starter assembly, tripping to disconnect the motor when excessive heat or overload conditions are detected. Used together with the SXLBO starter, the SA13A provides matched overload protection for small motors in Siemens control circuits.
