REX521BBHGLB01C motor protection relay is a relay designed specifically for motor protection by ABB. This relay plays a crucial role in the operation and protection of the motor, effectively preventing damage to the motor due to overload, short circuit, and phase loss faults.

Its main functions and characteristics are as follows:

Overload protection: The relay can detect the current of the motor. When the current exceeds the set value, the relay will act in a timely manner to cut off the power supply of the motor and prevent overload operation of the motor.

Short circuit protection: In the event of a short circuit fault in the motor, the relay can quickly detect abnormal current and cut off the power supply to prevent further damage to the motor and circuit caused by the short circuit.

Phase loss protection: When there is a phase loss in the power supply line of the motor, the relay can detect and cut off the power supply, avoiding the motor from running in a phase loss state and causing damage.

High sensitivity: The relay has a high sensitivity current detection ability, which can accurately judge the operating status of the motor and ensure the safe operation of the motor.

Easy to install and maintain: The REX521BBHGLB01C relay adopts standard interfaces and installation methods, making it convenient for users to install and maintain.

High reliability: This relay undergoes strict quality control and testing to ensure stable and reliable operation even in harsh industrial environments.

In summary, REX521BBHGLB01C motor protection relay is a powerful, stable, and easy-to-use motor protection device widely used in various motor protection scenarios, providing strong guarantees for the safe operation of motors.
