The REX521GHHPSH51G is a feeder protection relay manufactured by ABB. This relay is mainly used for the protection of the feed line, and its key role is to monitor the operating status of the feed line and take timely measures when abnormal conditions or faults are detected to prevent the fault from expanding and causing damage to the entire power system.

Specifically, the REX521GHHPSH51G feeder protection relay provides the following functions:

Overcurrent protection: When the current exceeds the rated current on the feed line, the relay will cut off the circuit in time to prevent equipment damage or fire caused by overcurrent.

Short-circuit protection: It can detect the short-circuit fault on the feed line and quickly cut off the circuit when the short-circuit current is detected to prevent serious damage caused by short circuit.

Ground fault protection: For power systems grounded at neutral points, the relay is also capable of detecting ground faults and taking appropriate protective measures to ensure the safe operation of the power system.

In addition, the REX521GHHPSH51G is highly reliable, with high-quality components and a rigorous test process to ensure stable operation of the relay. It is easy to install and maintain, and is suitable for a variety of industrial and civil power systems, such as factories, commercial buildings and residential buildings.

As an ABB product, the REX521GHHPSH51G feeder protection Relay inherits ABB’s outstanding quality and technical support in power and automation technology. Users can obtain reliable product performance, perfect technical support and timely after-sales service to ensure the stable operation and safety of the power system.
