£52.16
The ABB T16-2.3 Thermal Overload Relay (1SAZ711201R1031) is a reliable electromechanical motor protection device designed to safeguard three-phase motors against overload conditions and phase failure. Part of the trusted ABB T16 thermal overload relay series, it provides dependable protection for industrial motor starters, helping extend motor life while reducing costly downtime.
Designed for direct connection to compatible ABB mini contactors and block contactors, the T16-2.3 combines simple installation with proven motor protection. Featuring selectable automatic or manual reset, integrated temperature compensation and trip indication, it delivers dependable performance across a wide range of industrial applications.
With an adjustable current range of 1.7 to 2.3 A and Trip Class 10 protection, the ABB 1SAZ711201R1031 is ideal for protecting small motors used in conveyors, pumps, compressors, fans, machine tools and automated production equipment.
Thermal overload relays monitor motor current and disconnect the control circuit if excessive current is detected for an extended period. This prevents motor overheating, insulation damage and premature equipment failure while improving the reliability of industrial machinery.
The ABB T16 series is widely used alongside contactors in motor starters, providing cost-effective protection for pumps, conveyors, compressors, fans and manufacturing equipment across industrial automation systems.
