YRSA7-PK 1500V 4000A High-Speed Fuse

In large-scale energy storage projects, high voltage, massive power, and system stability and safety are crucial. The YRSA7-PK 1500V 4000A High-Speed Fuse from Galaxy Fuse is designed specifically for these demanding environments, providing exceptional protection for the next-generation energy storage systems (ESS).

In energy storage systems, which often feature DC circuits operating at hundreds of kilowatts or even megawatts, the fuse's ability to withstand high currents and respond quickly to faults directly impacts the safety of the entire system. The YRSA7-PK 1500V 4000A High-Speed Fuse is engineered with a rated voltage of 1500V DC, ensuring it can handle high-voltage applications such as battery clusters and DC busbars while maintaining excellent insulation and operational reliability. With 4000A of rated current, the fuse comfortably handles the large currents that modern energy storage systems demand, providing ample headroom for future system expansion without compromising safety or performance.

In energy storage systems, short-circuit faults are a significant risk. If one occurs, the consequences can be disastrous. To enhance safety, the YRSA7-PK 1500V 4000A High-Speed Fuse has passed the 250KA DC breaking capacity test, certified according to UL 248-13. This means that even under extreme short-circuit conditions, the fuse can quickly disconnect the current, preventing dangerous arc flashes and protecting core components from extensive damage. The super-fast fuse action ensures that the fuse responds to faults in milliseconds, minimizing the risk of equipment failure, and preserving system integrity.

Supporting this performance is the robust construction of the YRSA7-PK 1500V 4000A High-Speed Fuse. The fuse is housed in a high-strength ceramic body, offering excellent resistance to high temperatures, high pressures, and mechanical shock. The fuse's internal fuse element is made from silver alloy, a high-conductivity material that enhances both the fuse's responsiveness and overall operational efficiency. This combination ensures that the YRSA7-PK 1500V 4000A High-Speed Fuse remains reliable, even in the most extreme conditions.

Additionally, the YRSA7-PK 1500V 4000A High-Speed Fuse has earned CE and UL 248-13 certifications, ensuring compliance with international standards in regions such as Europe and North America. These certifications give the YRSA7-PK 1500V 4000A High-Speed Fuse global reliability, making it suitable for large-scale energy storage applications worldwide. Whether deployed in Europe or North America, the YRSA7-PK 1500V 4000A High-Speed Fuse complies with the highest standards of safety and performance, reducing certification costs and helping projects get up and running faster. You can check out more details on the official websites: UL 248-13 and IEC 60269-4.

As the global energy transition accelerates, energy storage plays a critical role, and its application is expanding rapidly. From centralized power plants to commercial and industrial energy storage, from distributed microgrids to off-grid independent systems, safety is always the top priority. The YRSA7-PK 1500V 4000A High-Speed Fuse, with its exceptional electrical performance and reliable action response, has already been successfully applied in numerous large-scale energy storage projects. Whether protecting DC busbars, battery clusters, or power conversion systems, the YRSA7-PK 1500V 4000A High-Speed Fuse has demonstrated its superior stability and reliability.

In real-world applications, such as a large-scale 100 MW energy storage plant, the YRSA7-PK 1500V 4000A High-Speed Fuse was deployed in the DC circuit between the battery clusters and the PCS (power conversion system) as the primary fast protection device. During operation, a short-circuit fault occurred due to an external disturbance, and the YRSA7-PK 1500V 4000A High-Speed Fuse immediately responded in milliseconds, isolating the fault and protecting critical equipment. Post-event analysis confirmed that the fuse operated flawlessly without misfiring or delays, showcasing its excellent engineering adaptability and high safety trustworthiness.
