Low Voltage Fuse-type Disconnecting Switch is a combined electrical appliance consisting of knife switch and fuse, which has two structures of horizontal installation and vertical installation. It is suitable for outdoor distribution lines of 500 V and 50 Hz, and can be used for protection and overload protection at low voltage side of transformers. It can connect and disconnect the no-load transformer, no-load line and rated working current under certain conditions. It should be installed in a place with ambient temperature from -40°C to +25°C, and altitude not more than 2,000 m. Execution standard of product: GB/T 1985-2014 High Voltage AC Disconnectors and Earthing Switches.
