Product questions
What is the current setting range and trip class of ABB 1SAZ411201R2002?
The TA110DU-110M has an adjustable current setting range of 80–110 A and a trip class of 10A. Check the motor nameplate current and the protection requirements before selecting it.
What protection and auxiliary contacts does the TA110DU-110M provide?
This three-pole thermal overload relay is described as providing motor overload and phase-failure protection. It has one normally open and one normally closed auxiliary contact, plus test and stop functions.
Can the TA110DU-110M be used with my existing motor starter?
The 80–110 A setting range alone does not establish compatibility with a particular starter. Provide the contactor and motor nameplate details, and the equipment model and serial number where available, so the mounting and protection requirements can be checked.
