ABB REX010 Earth Fault Protection Unit

ABB's REX010 Ground Fault Protection unit is a device designed to protect electrical systems from ground faults. The device is mainly used in the medium and low voltage power distribution system, and has the function of detecting and cutting off the ground fault, which can effectively reduce the risk of safety accidents such as fire and electric shock.

The REX010 Ground Fault protection unit monitors changes in current and voltage in real time and quickly cuts off the fault line when it detects a ground fault to prevent the accident from spreading. The device also has a high-precision fault location function, which can help users quickly find the fault point and repair it, thus improving the reliability and safety of the entire system.

In addition to the basic ground fault protection function, the REX010 also has some other practical functions, such as overcurrent protection, overload protection and undervoltage protection. These functions can provide users with a full range of protection to ensure the normal operation of the entire electrical system.

Overall, ABB's REX010 ground fault protection unit is an efficient and reliable electrical protection device for a wide range of applications in industrial, commercial and civil buildings. By using REX010, users can reduce unnecessary electrical accidents and losses and improve the safety and reliability of the entire system.
