ABB KUC755AE105 3BHB005243R0105 Unit Control Module

The ABB KUC755AE105 3BHB005243R0105 unit control module is a high-performance control unit produced by ABB. It is widely used in the field of industrial automation. The following is an introduction to this module:
I. Main Functions
Delay phase overvoltage protection: By monitoring the three-phase voltages, this function protects electrical equipment and its insulation from overvoltage, preventing damage to exposed primary and secondary equipment in the power system.
Fuses fault monitoring: Continuously monitors the AC voltage circuit between the voltage transformer and the terminals. In the event of a fault in the AC voltage secondary circuit, different output signals are used to prevent the operation of distance protection and other voltage-related functions.
Special Function Input: Used to connect the auxiliary contacts of a miniature circuit breaker (MCB) to ensure the correct operation of the function when all three measured phase voltages are simultaneously interrupted, and when there is no additional Δ current and Δ voltage algorithm in the function block.

Technical Features
High Reliability: Utilizing high-quality electronic components and advanced circuit design, the module ensures high reliability and stability.
Adaptability: Capable of adapting to various application environments and requirements, it has high configurability and flexibility.
Easy Maintenance: Equipped with fault diagnosis and recording functions, it facilitates subsequent fault troubleshooting and maintenance.
Communication Function: Equipped with standard communication interfaces such as RS-485 and Ethernet, for communication with the superior management system or monitoring system, supporting remote monitoring and control functions.
