£159.23
The ABB 1SAX111001R1104 is a reliable and accurate E16DU-6.3 electronic overload relay designed to provide advanced motor protection against overload conditions, phase failure and excessive current in industrial control systems. As part of the ABB E16DU electronic overload relay range, it delivers fast protection, adjustable settings and dependable operation for motor starters and automation applications.
This self-powered electronic overload relay requires no external auxiliary supply and provides improved accuracy compared with traditional thermal overload relays. It features selectable trip classes, temperature compensation, automatic or manual reset selection, test and stop functions, trip indication and direct connection to compatible ABB contactors.
With an adjustable current setting range of 2.0–6.3 A, a 6.3 A rated operational current and three protected poles, the ABB E16DU-6.3 is suitable for reliable protection of small industrial motors and motor control assemblies.
Electronic overload relays such as the ABB E16DU-6.3 protect motors by monitoring operating current and disconnecting the control circuit when abnormal conditions occur. This helps prevent motor damage caused by overloads, phase loss and excessive thermal stress.
The E16DU range provides accurate protection, flexible trip settings and convenient integration with ABB contactors, making it suitable for industrial motor starters, automation equipment and machine control systems.
