Duckbill Contact for Vacuum Circuit Breaker has many advantages:

Compact Structure – Flexible Operation

Simple and compact design with no complex moving parts. The tension spring mechanism ensures consistent contact pressure without requiring frequent adjustment. Fits standard withdrawable breaker platforms with minimal maintenance.

Good Thermal and Electrical Conductivity

The duckbill contact structure uses multiple contact points between the contact fingers and the fixed copper bar, maximizing contact surface area. This reduces contact resistance, minimizes heat generation at rated current, and improves overall efficiency. The design also allows easy adjustment of the trolley position during installation.

Duckbill Contact for Vacuum Circuit Breaker has many applications:

primary conductive circuits of high-voltage vacuum circuit breakers
