1SAZ331201R2003

ABB 1SAZ331201R2003 TA110DU-90 Thermal Overload Relay is a three-pole electromechanical motor protection relay designed to protect AC motors against overload and phase-failure conditions. It provides an adjustable current setting range of approximately 65 A to 90 A, allowing the protection level to be matched to the motor’s rated full-load current. The TA110DU-90 operates with Trip Class 10A, making it suitable for motors with normal starting characteristics. It is designed for integration with compatible ABB contactors to create compact and reliable motor-starter assemblies for industrial control applications.
