? Description:
The ABB TA25DU-1.4M is a compact and reliable thermal overload relay designed to protect electric motors against overloads, phase loss, and phase unbalance within the adjustable current range of 1.00 to 1.40 A. It is built for direct integration with ABB contactors and is widely used in motor control centers and industrial automation.

? Key Features:

• Adjustable current setting: 1.00 – 1.40 A

• Trip class: Class 10A (ideal for standard motor protection)

• Phase failure protection: Ensures shutdown during loss of phase

• Reset types: Selectable manual or automatic reset

• Ambient temperature compensation: Reliable performance in different environmental conditions

• Test/STOP button: For easy testing and emergency disconnection

• Mounting: Direct mounting on ABB A-line contactors (e.g., A9–A26)

• Operating temperature: -20°C to +60°C

• Standard compliance: Meets IEC/EN 60947-4-1 and related industrial safety norms

• Applications: Suitable for low-power motor loads such as conveyors, small pumps, and HVAC systems
