As you can see, our products are ready for shipment and delivered safely and on time to customers worldwide through standardized wooden box packaging and container transportation. Choosing SARAH means choosing professional, reliable, and global partners.
SARAH Electric is a manufacturer of 12KV Load Break Fuse Cutout. This product is a load switch type protection device specifically for medium and high voltage distribution networks ranging from 10kV to 38kV. Unlike traditional fuses that only have short-circuit protection function, the LBSJC series adopts a unique arc extinguishing device and dual fuse structure, enabling it to operate under load.
This means that operation and maintenance personnel can safely perform line switching operations without power interruption, greatly improving power supply reliability and operation and maintenance efficiency.
Advantage
1. The 1.12KV Load Break Fuse Cutout is equipped with a high-performance arc extinguishing cover and a specially designed arc contact. During the operation, the arc is rapidly elongated and cooled, ensuring safe and non reigning interruption of the load current at rated currents of 100A to 200A. This feature makes it a perfect replacement for the traditional combination of "isolation switch+fuse", simplifying the distribution structure and reducing equipment costs.
2. It adopts a dual protection design of "main fuse+nozzle fuse".
-Main fuse: responsible for daily overload protection, with sensitive response.
-Spray nozzle fuse: It melts instantly in the event of a short circuit fault, producing a large amount of arc extinguishing gas. With the help of an arc extinguishing cover, it quickly extinguishes the arc, ensuring that the equipment remains safe under the impact of a short circuit current of 8kA to 10kA.
3. High strength ceramic or silicone rubber composite insulators are used, which have excellent hydrophobicity and anti pollution flashover ability. Its leakage distance design is sufficient (up to 720mm), which can effectively prevent flashover accidents in harsh environments such as humidity, salt spray, and dust, ensuring long-term stable operation in cold, hot, and coastal areas.
