TA2X2.2-32 ABB TThermal overload relay Precise thermal protection
provided medium small power motors
Product Overview
ABB TA2X2.2-32 is A high-performance thermal overload relay in the
ABB TA2X series, specifically designed to protect small and
medium-sized three-phase asynchronous motors (rated current 2.2-32
A) from overload and phase loss faults. This model is equipped with
one normally open (NO) auxiliary contact and supports automatic
reset function. It can be directly assembled with ABB A series
contactors to form an integrated motor starting and protection
unit. With high reliability, compact structure and international
certification, it is widely used in industrial control cabinets,
building automation systems and OEM equipment.
Key features
✅ precise overload protection
Adopting the principle of bimetallic strip thermal sensing, the
tripping characteristic complies with the IEC/EN 60947-4-1 standard
(Class 10A), ensuring that the power supply of the motor is cut off
in time when overloaded to prevent winding damage.
✅ phase loss protection function
It is equipped with a built-in three-phase current imbalance
detection mechanism. Once any phase is disconnected, it will
trigger a trip to prevent the motor from overheating and burning
out due to single-phase operation.
✅ space-saving & flexible installation
The width is only 45mm
Supports 35mm DIN rail mounting
It can be directly assembled on the right side of ABB A series
contactors (such as A30, A40), and the main circuit is
automatically connected without the need for additional wiring
✅ security compliance certification
It has passed global mainstream certifications such as CE, UL, CSA,
CCC, and TUV, complies with RoHS and REACH environmental protection
requirements, and meets international project access standards.
✅ is easy to operate and maintain
The transparent window allows for a direct view of the tripping
status. The reset button is easy to operate. It resets
automatically by default. A manual reset module can also be
optionally equipped to enhance operational safety.
