Product Description

The ABB TA2X thermol overload relay is an electrothermal protective device designed for reliable motor protection against overloads and phase loss. It integrates seamlessly with ABB contactors (e.g., AX, A2X series) to form compact starter solutions. Utilizing a bimetallic strip mechanism, it disconnects circuits during excessive current or phase failure, preventing motor damage. Key features include adjustable trip settings, temperature compensation, and dual reset modes.

Standard Features

Ideal for industrial automation, machinery, and electrical control panels, it ensures operational safety and compliance with IEC standards.

  • Overload & phase-loss protection: Detects imbalances and overloads to prevent motor burnout

  • Adjustable trip settings: Customizable current settings via dial (e.g., 0.1–50A)

  • Temperature compensation: Operates reliably up to +60°C

  • Dual reset modes: Manual (R) or automatic (RO) reset options

  • Test/Stop function: Allows manual triggering for safety checks

  • Auxiliary contacts: Includes 1 NO (97-98) and 1 NC (95-96) for control signaling

  • High durability:Mechanical/electrical lifespan of 1 million operations
