The ABB TA42DU-32M is a genuine ABB TA42DU thermal overload relay with an adjustable setting range of 22.0-32.0 A, used to protect three-phase motors against overload, phase failure and long starting. It mounts directly on ABB AX32, AX40 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 TA42DU 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.

How to Read the ABB Part Number TA42DU-32M
- TA – ABB thermal overload relay
- 42 – frame size / maximum current class of the relay family (TA42DU)
- DU – direct mounting on the contactor, universal (AC/DC) main circuit
- 32M – upper limit of the setting range (22.0-32.0 A), M = current generation with 1 NO + 1 NC contacts and trip class 10A
Typical Applications
Direct-on-line and star-delta motor starters, pumps, fans and compressors, conveyor and packaging machines, HVAC units, and any control panel where an ABB AX, AF or A series contactor needs thermal motor protection.

Frequently Asked Questions
What is the setting range of the ABB TA42DU-32M?
It is adjustable from 22.0-32.0 A (motor full-load current), with trip class 10A according to ABB technical data.
Which contactors does the TA42DU-32M mount on?
It mounts directly on ABB AX32, AX40 contactors, or on a separate base (DB80 kit) when stand-alone mounting is needed.
Does it protect against phase failure?
Yes, the TA42DU 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?
