ABB EOT16U3P4-P Electronic Overload Relay for Motor Protection

ABB EOT16U3P4-P Electronic Overload Relay for Motor Protection is a three-pole electronic protection device designed to guard three-phase motors against overload and phase failure when used with ABB contactors in low-voltage motor control circuits. It integrates into standard motor-control panels and provides fast, reliable tripping to prevent winding damage and reduce nuisance trips in unbalanced loads, making it suitable for pumps, fans, conveyors, machine tools, and other industrial motors where continuous operation is critical. As part of ABB's electronic overload protection family, the EOT16U3P4-P monitors motor current and initiates a protective disconnect when preset limits are exceeded, helping extend motor life and maintain process uptime. Its compact form factor and straightforward wiring support easy integration with existing ABB control gear and panel layouts, enabling a tidy protection block within common cabinet footprints. The device is designed to coordinate with ABB's motor protection and control ecosystem, offering consistent performance with ABB contactors and MCCs and contributing to safer motor starts and reliable shutdowns in automation systems.
