ABB TA Thermal Overload Relays

The ABB TA Thermal Overload Relay provides robust protection for three-phase motors against overload and phase loss conditions. Designed for integration with ABB’s A, AF, AL, and AX series contactors, it operates at rated voltages up to AC 690 V or DC 800 V. Utilizing a bimetallic strip mechanism, it trips when excessive current heats and bends the strip, disconnecting the motor circuit via auxiliary contacts. Ideal for industrial applications like machinery, pumps, and HVAC systems, it ensures motor longevity and operational safety.
