Description

Cylindrical Fuse Links are essential components designed to protect semiconductor parts and equipment from short-circuits (type aR) and to safeguard motors (type aM). These fuses are rated for voltages up to 690V and currents up to 125A, making them suitable for various applications in electrical lines. They operate at a working frequency of 50Hz AC and have a rated breaking capacity of up to 100kA, ensuring reliable performance under demanding conditions. Compliance with GB 13539 and IEC 60269 standards further underscores their reliability and effectiveness in providing overcurrent protection.

Applications include protection against overload and short-circuit situations, making them ideal for industrial and commercial use. The innovative design features a variable cross-section fuse element made from pure metal, encapsulated in a high-duty ceramic or epoxy glass cartridge. The fuse tube is filled with chemically treated high-purity quartz sand, serving as an effective arc-extinguishing medium. Additionally, the dot-welding of fuse element ends to the caps guarantees a secure electrical connection. A striker may be attached to the fuse link for immediate activation of a micro-switch, enabling various signaling options or automatic circuit interruption. Custom fuse designs are also available per customer specifications.
