Fixed Contact

This static contact is widely used in KYN28 (GZS1) and other withdrawable switchgear as the fixed interface for the circuit breaker compartment. With a lower current rating of 630A and a reduced diameter of 35mm, it is ideally suited for compact switchgear configurations and distribution networks where space efficiency and reliable performance are paramount.

The Fixed Contact (Static Contact) is a critical stationary component within high-voltage switchgear, designed to interface seamlessly with the moving contacts (such as tulip contacts) of a vacuum circuit breaker. Machined from high-purity T2 copper, this contact ensures optimal current transfer with minimal resistive losses.
