　　HAFAABAAABE1BCA1XE Other names:

　　Microcomputer comprehensive protection HAFAABAAABE1BCA1XE

　　HAFAABAAABE1BCA1XE arc protection relay

　　Voltage protection device HAFAABAAABE1BCA1XE

　　RE401-AAA relay protection device is an important electrical safety device that prevents equipment damage and accidents by automatically cutting off abnormal circuits. Designed for power systems, it is used to detect and respond to arc faults in a timely manner to protect the safety of personnel and equipment. It is suitable for electrical equipment protection in various power systems and industrial control systems.

　　Main functions

　　Arc detection: Using advanced algorithms, real-time monitoring of electrical parameters such as current and voltage is carried out to quickly detect characteristic signals generated by arcs.

　　Quick response: Once an arc is detected, a trip signal is immediately issued to quickly cut off the fault circuit to prevent the arc from expanding and causing a fire.

　　High sensitivity: It has a high sensitivity to various types of arc faults, ensuring timely detection of faults.

　　High reliability: Highly reliable hardware and software design is adopted to ensure long-term stable operation of the equipment.

　　Technical features

　　Configurability: Through software configuration, it can adapt to different application scenarios and meet different protection needs.

　　Modular design: Compact structure, easy installation, and equipped with a friendly user interface for easy operation and maintenance.

　　Compliance with international standards: The device complies with relevant international standards and specifications to ensure its applicability and reliability worldwide.

　　Self-test system: The built-in self-test system can monitor the operating voltage, the integrity of the wiring between modules, and the integrity of the optical fiber connection. Once a fault or abnormal condition is detected, an alarm is immediately issued to the operator.

　　High-speed output: The main module has two high-speed, isolated, insulated gate bipolar transistor (IGBT) output devices, which can be used to disconnect the circuit breaker to ensure rapid removal of the fault.

　　Application scenarios

　　Low voltage power distribution system: used to protect electrical equipment in low voltage power distribution system, such as switch cabinet, distribution box, etc.

　　Industrial control system: used to protect electrical equipment in industrial control system to ensure stable operation of the system.

　　Data center: used to protect the power distribution system of data center to prevent data loss or equipment damage caused by arc fault.

　　Additional functions

　　The HAFAABAAABE1BCA1XE arc protection device module is also equipped with two expansion ports, each of which can connect up to five expansion modules.

　　Multiple modules of REA101 can be interconnected through optical fiber link communication or REA105 intermediate expansion module.

　　The main module has two high-speed, electrically isolated, insulated gate bipolar transistor (IGBT) output devices (HSO1 and HSO2) that can be used to disconnect the circuit breaker.

　　A heavy-duty relay output (TRIP3) is provided, which can be used as circuit breaker failure protection (CBFP) to trip the upstream circuit breaker or alarm output.

　　The main module has adjustable three-phase overcurrent or two-phase and neutral overcurrent status monitoring function, which can improve the reliability of arc fault detection by eliminating light that is not related to arc faults (such as unnecessary circuit breaker tripping caused by photographic flash).

　　The built-in self-test system can simultaneously monitor the operating voltage, the integrity of the wiring between the main module and the expansion module, and the fiber optic connection between the main modules. Once a fault or abnormal condition is detected, the self-test system will issue an alarm to the operator. After detecting a fault, the system will lock the module to prevent malfunction caused by it.
