FN7 series load switch is a kind of high-voltage electrical appliance, which is used for breaking circuit in power system or controlling the load of circuit. The following are some information about FN7 series load switch:
Design: The FN7 series load switch has a compact structure and generally includes a reliable mechanical connection and a spring mechanism. They typically use an arc chamber with a ceramic sleeve and a reversing operating mechanism to protect the load circuit.
Application: FN7 load switch is widely used in high-voltage power systems such as substations, distribution stations, factories and large public facilities. They are commonly used in load switches and short circuit protection devices on medium and low voltage distribution lines.
Specifications: The rated voltage range of FN7 series load switches is usually 10KV to 40.5KV, and the rated current range can vary from 630A to 4000A. At the same time, FN7 series load switches can also be selected and designed according to specific needs.
Operation: FN7 series load switch has two modes of operation, manual and electric, and the common electric mode is DC/AC drive. During manual operation, the switch will emit obvious sound and light indication to prevent misoperation.
Safety: FN7 series load switch adopts advanced technology and materials to ensure safety and reliability. They also work well in high temperature, high humidity or polluted environments and have protective features such as shields and arc resistant materials.
