This manual describes the SHK‑FSR large‑capacity high‑speed switch, including its structure (bridge body FS, fuse FU, nonlinear resistor FR, and control unit) and operating principle. It explains how the device quickly interrupts fault currents within 0.15 ms to 0.5 ms, limiting over‑voltage and protecting downstream equipment.
The document also covers environmental requirements, ordering information, packaging, transport, and technical support. It provides installation conditions such as temperature range, altitude limits, humidity, and safety notes for reliable operation in power systems. This manual is written in Chinese.
