Main features and advantages of the product:
One of the most impressive features of ABB REF615C_E HCFEAEAGAABC2BAA11E is its comprehensive protection capability. It provides time limited and instantaneous overcurrent protection. This means it can detect slow-moving and sudden overcurrent situations. For example, when a motor starts, it usually absorbs a large starting current, and this relay can distinguish between this normal starting current and a true overcurrent fault, avoiding unnecessary tripping.
Negative sequence overcurrent protection is another important function. Unbalanced loads in three-phase systems may lead to negative sequence currents, which can cause damage to electrical equipment. ABB REF615C_E HCFEAEAGAABC2BAA11E is capable of detecting these negative sequence currents and taking appropriate measures to protect the equipment.
The relay also provides phase sequence discontinuity protection. In the power system, a phase breaking or disconnection may cause uneven operation of the motor and other equipment. ABB REF615C_E HCFEAEAGAABC2BAA11E can quickly identify such phase sequence discontinuities and isolate the affected parts.
In terms of hardware design, ABB REF615C_E HCFEAEAGAABC2BAA11E has a compact design. This makes it suitable for installation in various types of switchgear, even in limited space. Its sturdy structure ensures that it can withstand the harsh electromagnetic environment commonly found in industrial environments. The device is designed to operate within a wide temperature range of -25 ° C to+55 ° C, making it suitable for different climate conditions worldwide.
Compatibility is a major advantage of this device. It supports multiple communication protocols, including IEC 61850 (1st and 2nd editions, supporting high availability seamless redundancy – HSR and parallel redundancy protocol – PRP), Modbus, DNP3, and IEC 60870-5-103. This enables it to effectively communicate with other devices in the distribution network, such as remote terminal units (RTUs), programmable logic controllers (PLCs), and human-machine interfaces (HMIs). This seamless communication enables centralized real-time monitoring and control of feeders, improving the overall efficiency and reliability of the power system.

ABB REF615C_E HCFEAEAGABC2BAA11E
Application areas:
Taking large manufacturing factories as an example. The factory is equipped with a large number of machinery, all powered by a complex electrical feeder network. Once sudden electrical faults such as overcurrent caused by motor failure occur, the entire production line may come to a standstill, resulting in huge economic losses. And ABB REF615C_E HCFEAEAGAABC2BAA11E is deployed here to prevent such situations from happening. It continuously monitors the electrical parameters of the feeder and can quickly detect any abnormal situations. If overcurrent occurs, it will take immediate action, such as tripping the circuit breaker to isolate the faulty part. This ensures the safety of the equipment and minimizes production downtime to the greatest extent possible.
The power plant also heavily relies on ABB REF615C_E HCFEAEAGAABC2BAA11E. The stable operation of the power grid is crucial for coal-fired, hydroelectric, and nuclear power plants. This device monitors the feeders that transmit power from the generator to the grid. By preventing short circuits and ground faults, it helps maintain the integrity of power supply and ensure stable power supply to users.
