The ABB T16-13 Thermal Overload Relay (1SAZ711201R1045) is a dependable electromechanical motor protection device engineered to safeguard three-phase motors against overload conditions and phase failure. As part of the trusted ABB T16 thermal overload relay series, it delivers reliable overload protection that helps minimise downtime, improve equipment reliability and extend motor service life. Designed for use with ABB contactors, it provides an efficient solution for industrial motor starter assemblies.
The relay incorporates advanced protection features including temperature compensation, phase loss sensitivity, selectable automatic or manual reset, trip indication and a trip-free mechanism. Direct mounting onto compatible ABB mini and block contactors simplifies installation while maintaining a compact motor starter design.
With an adjustable overload setting of 10 to 13 A and Trip Class 10 protection, the T16-13 is ideal for safeguarding industrial motors used in conveyors, pumps, compressors, fans, machine tools, packaging equipment and automated production systems.
