The FB series auxiliary switches are among the supporting components for high-voltage switchgear, suitable for controlling the closing, opening, interlocking, and signal circuits of various high-voltage switch operating mechanisms, and can also be used as changeover or combination switches. Their large-capacity on-off capability effectively overcomes the drawbacks of other auxiliary switches, such as limited capacity and short contact life, significantly extending the product's service life. They are an effective alternative to other similar auxiliary switches.
