The ABB TA110DU-110 is a genuine ABB TA110DU thermal overload relay with an adjustable setting range of 80-110 A, used to protect three-phase motors against overload, phase failure and long starting. It mounts directly on ABB A95, A110, AE95, AE110 contactors, giving a compact starter with no extra wiring for the main circuit. Trip class 10A, ambient temperature compensation, a trip indicator, a test function and a selectable manual or automatic reset make it the standard protection relay on pump, fan, compressor and conveyor starters, and the TA110DU family is one of the most frequently replaced motor protection parts on European and Asian built machinery across Iraq, Saudi Arabia, the UAE and the wider Arab region.

Frequently Asked Questions
What is the setting range of the ABB TA110DU-110?
It is adjustable from 80-110 A (motor full-load current), with trip class 10A according to ABB technical data.
Which contactors does the TA110DU-110 mount on?
It mounts directly on ABB A95, A110, AE95, AE110 contactors, or on a separate base (DB80 kit) when stand-alone mounting is needed.
Does it protect against phase failure?
Yes, the TA110DU relays are phase-failure sensitive and temperature compensated, and have a trip indicator, test button and manual/automatic reset selector.
What auxiliary contacts does it have?
1 NO + 1 NC: the NC contact opens the contactor coil circuit on trip and the NO contact signals the fault.
