Product details: REX521BBHGLB01C ABB feeder and motor protection relay

REX521BBHGLB01C is a feeder and motor protection relay produced by ABB, belonging to the REX 521 series. This product not only has excellent feeder protection function, but also provides a complete set of value-added information service software package, including technical data, user documentation, wiring diagrams and other basic information, to ensure that the relay runs smoothly and efficiently from installation, configuration, debugging and its service life.

The new features of REX 521 feeder protection relay make it more widely applicable to the protection, measurement, monitoring, and control needs of power systems. It is typically applied in neutral ungrounded systems, resonant grounded systems, neutral directly grounded systems, and resistance grounded systems, and can meet protection functions such as quick break, overcurrent, and zero sequence grounding between incoming and outgoing lines. In addition, the powerful protection function of REX 521 also allows it to be applied to large and medium-sized medium voltage motor protection units.

REX 521 is an important member of ABB’s intelligent terminal series product line, which includes basic protection relays and integrates power system protection, measurement, and monitoring functions. The enhanced REX 521 not only has a series of new protection functions, but also provides a large number of monitoring functions such as power quality monitoring. In order to meet the needs of users in the Chinese market, special protection functions such as acceleration before and after reclosing have been added, and a fully Chinese human-machine interface display has been provided, making debugging and operation very convenient

Product details and parameters: REX521BBHGLB01C ABB feeder and motor protection relay
Design purpose: REX521BBHGLB01C feeder and motor protection relay is designed for protection, control, measurement, and monitoring in medium voltage power systems, suitable for incoming, outgoing, and substation protection.
Input configuration: This relay is equipped with AC input terminals for conventional current and voltage transformers, and also provides hardware versions with current and voltage sensor inputs.
Based on a multiprocessor environment: REX521BBHGLB01C is based on a multiprocessor environment, and the human-machine interface (HMI) includes an LCD (liquid crystal display) with different views for local use, and can notify users through indicator information.
REX521BBHGLB01C ABB application areas:

REX 521 Technology Summary: Towards Intelligent Substation Integrated Automation. In addition to protection functions, REX 521 also provides the following features: comprehensive measurement functions for monitoring user networks, high sampling rate fault recording modules integrated for accurate capture and analysis of faults, local/remote circuit breaker control, configurable multi turn automatic reclosing, circuit breaker status monitoring, measurable total harmonic distortion (THD) of voltage or current for power quality monitoring, fully Chinese interface identification and display information.
