Scope of Application
The HK8 series load switch (hereinafter referred to as the "switch") has a rated voltage of 220V, with a maximum voltage rating of 250V, and is designed for a rated frequency of 50 Hz. It can handle rated currents of 25A and 63A, making it suitable for use in industrial and residential power distribution systems—specifically for infrequent manual switching operations to isolate power sources, as well as for protecting distribution circuits against overloads and short circuits. Additionally, the switch features a clearly visible breaking point when disconnecting, which is why it has become widely adopted in urban and rural grid renovation projects, particularly in household switch boxes and meter boxes.
