REX521GHHGSH05G ABB Microcomputer integrated relay protection

Description

ABB’s globally recognized VD4 circuit breaker REX521GHHGSH05G has developed into a safer, more intelligent and more sustainable feature through advanced digital functions
The new intelligent VD4 circuit breaker reduces the power failure risk by 30% and improves the operation and maintenance efficiency by 60%
VD4 evo is compact and configurable. REX521GHHGSH05G is designed to be “plug and play”, easy to install and upgrade

With the transformation of the global power system, ABB continues to lead its seamless digital transformation and develop its highly respected VD4 medium voltage (MV) circuit breaker
The new VD4 evo has changed the excellent operation and cost-effectiveness of the modern power distribution REX521GHHGSH05G application. It adopts the popular existing product series (established in more than 2 million devices in more than 100 countries/regions) and rapidly pushes it to the digital future
The VD4 evo is designed with Industry 4.0 sensor enhancements for all thermal, mechanical and electrical parameters, as well as an advanced central monitoring unit for 24/7 real-time analysis. By providing key information through simple and intuitive dashboards, this approach provides unparalleled visibility into device data, status, and condition from anywhere in the world. This is a diagnostic report and alarm notification based on ABB expertise.
The ability to identify and solve problems in advance has brought a series of significant operational and financial benefits to users such as panel manufacturers and original equipment manufacturers (OEMs), thereby reducing the risk of power failure by 30% ¹， And improved operation and maintenance efficiency by 60% ²， In addition, technological improvements make it easier to predict wear and extend overall life and production, saving thousands of dollars per solution compared to traditional medium voltage switchgear.
The ultra compact design and energy-saving operation of VD4 evo have also achieved sustainability, and it has fully passed the Environmental Product Declaration (EPD) certification. Compared with the traditional medium voltage circuit breaker, it is 15% smaller. As an important part of the digital switchgear, it also plays a role in saving up to 150 tons of CO2 emissions in the 30 year life of the panel unit, equivalent to 1 million kilometers of long-distance economic flights. Similarly, the ability to make better decisions in all aspects of installation and maintenance work can ensure the high-level safety and protection of personnel and maintenance personnel
