The ABB 1SAZ711201R1021, also known as the T16-0.74 Thermal Overload Relay, is a compact and dependable electromechanical motor protection relay designed to protect three-phase motors against overload conditions and phase failure. As part of the trusted ABB T16 Thermal Overload Relay series, it delivers reliable motor protection while helping reduce downtime and extend motor service life.
The T16-0.74 incorporates Trip Class 10 protection, temperature compensation, selectable automatic or manual reset, phase loss sensitivity, integrated STOP and TEST functions and a clear trip indication. Designed for direct mounting onto compatible ABB mini and block contactors, it offers quick installation and dependable operation within industrial motor starter assemblies.
With an adjustable current setting range of 0.55 to 0.74 A, the ABB 1SAZ711201R1021 is ideal for protecting small three-phase motors used in conveyors, pumps, compressors, fans, OEM machinery and industrial automation systems.
Thermal overload relays continuously monitor motor current and disconnect the motor circuit whenever prolonged overload conditions occur. This protects motors against overheating, reduces maintenance costs and helps maximise the operational life of industrial equipment.
The ABB T16 series combines dependable overload protection, phase failure detection and straightforward installation, making it an excellent solution for industrial motor starters, machine builders and OEM automation equipment.
