The 7UM5121-2EB01-0BB0 is a state-of-the-art generator protection relay designed for advanced overcurrent-time protection functions. This device ensures optimal performance in electrical applications by providing robust features such as undervoltage protection, and current raise/reduction capabilities.

With its unique stepped characteristic for unbalanced load conditions, this relay incorporates thermal replica technology to safeguard your systems efficiently. It not only measures stator earth-fault voltages but also offers direct earth-fault measurement to enhance your operational reliability.

Compatible with DC voltage systems, this version V3 relay operates seamlessly at rated currents from 100 to 125V AC and is equipped with auxiliary voltage functions for DC 24V and 48V. Installed in a 7XP20 case, it is ideal for both panel flush and cubicle mounting without a glass cover.

Manufactured by Siemens in Germany, the 7UM5121-2EB01-0BB0 is designed with a serial interface for control of electrically isolated systems, making it a vital component for enhancing the safety and efficiency of your electrical installations.
