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.
High Conductivity Material
Precision-machined from solid T2 copper, offering superior electrical and thermal conductivity compared to standard alloys.
Surface: Silver-plated (Ag) for optimal contact reliability.
Applications: Widely used in Vacuum Circuit Breakers (VCBs), GIS, and medium-to-high voltage switchgears.

Precision-machined from solid T2 copper, offering superior electrical and thermal conductivity compared to standard alloys.
Silver-Plated Finish
Manufactured with a mature silver-plating electroplating process to prevent oxidation, reduce contact resistance, and ensure consistent product quality (Optional/Standard).
Robust Design
Engineered to withstand high levels of short-circuit current and thermal stress without deformation or breakdown.
Secure Fit
Dimensional accuracy of 35mm diameter with a length of 72mm (82mm including base) ensures secure installation and consistent alignment with the moving contact.
