The ABB TA200DU-135 is a genuine ABB TA200DU thermal overload relay with an adjustable setting range of 100-135 A, used to protect three-phase motors against overload, phase failure and long starting. It mounts directly on ABB A145, A185, AF145, AF185, AF190, AF205 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 TA200DU 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 TA200DU-135?
It is adjustable from 100-135 A (motor full-load current), with trip class 10A according to ABB technical data.
Which contactors does the TA200DU-135 mount on?
It mounts directly on ABB A145, A185, AF145, AF185, AF190, AF205 contactors, or on a separate base (DB80 kit) when stand-alone mounting is needed.
Does it protect against phase failure?
Yes, the TA200DU 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.
Is this a genuine ABB part and how fast can it ship?
RendatSP supplies genuine ABB TA200DU-135 relays, order code 1SAZ421201R1003, quotes within hours and ships worldwide including Iraq, Saudi Arabia and the UAE.
