ABB Overload Relay

The ABB Overload Relay is engineered to provide reliable motor protection by safeguarding electrical systems against overloads, phase loss, and excessive heating. Built with advanced sensing technology and a robust construction, ABB relays ensure stable performance across industrial, commercial, and automation applications.

Accurate Overload Protection

ABB overload relays detect abnormal current rise and trip instantly to protect motors from damage. Their precision thermal and electronic mechanisms provide dependable protection for both small and heavy-duty motors.

Compact, Panel-Friendly Design

With a modular and compact profile, these relays integrate easily with ABB contactors and motor starters. The simplified mounting system ensures fast installation and reduced panel space.

Adjustable Current Settings

The relay allows flexible adjustment of current range, making it suitable for a wide variety of motors. This adaptability ensures accurate protection tailored to specific load requirements.
