1SAZ411201R2002

ABB 1SAZ411201R2002 TA110DU-110M Thermal Overload Relay is an electromechanical motor-protection relay designed to protect industrial three-phase motors against overload and phase-failure conditions. Its adjustable thermal current range of 80 A to 110 A allows the protection setting to be matched to the motor’s rated full-load current. The relay operates according to Trip Class 10A, making it suitable for standard motor-starting applications. The TA110DU-110M is designed for direct mounting on compatible ABB contactors, providing a compact motor-starter solution. ABB specifies 3-pole construction, 1 normally closed auxiliary contact and 1 normally open auxiliary contact, enabling the relay to interrupt the contactor control circuit after a trip while also providing alarm indication, PLC feedback, or remote fault signaling.
