Product Overview
The FK series auxiliary switch is one of the supporting components for high-voltage switchgear. It is a new type of auxiliary switch developed to meet the current application requirements of auxiliary switches in the power industry. Compared with commonly used auxiliary switches such as F6 and F9, it offers more flexible angle control and can achieve various special switching operations. Compared with F10 auxiliary switches, its contact capacity is more than doubled, which can better meet the high current requirements of the high-voltage switch industry. It is widely applicable for controlling the closing, opening, interlocking, and signal circuits of various high-voltage switch operating mechanisms, and can also be used as a transfer or combination switch.
