Description
The Copper Contact Arm is a critical component in high voltage vacuum circuit breakers (VCBs), designed to ensure reliable and efficient operation. Crafted from high-quality red copper, this contact arm serves as one of the conductive parts within the VCB, providing excellent electrical conductivity. Our vulcanized contact arm eliminates the need for a sleeve, simplifying the product structure and enabling miniaturization of the switch. With a vulcanized layer thickness of 2-4mm, it can withstand a remarkable 20,000 volts of power frequency withstand voltage per millimeter, ensuring safety and performance even in demanding conditions.
