LYB009 Contact Arm for High-Voltage Vacuum Circuit Breaker – Premium Silver-Plated Copper Conductive Sleeve

The LYB009 is a high-performance contact arm (conducting sleeve) specifically engineered for vacuum circuit breakers (VCB) and high-voltage switchgear. Precision-crafted from high-purity copper, this component features a bi-tonal finish: a polished silver-plated body for maximum conductivity and a specialized copper-toned head for optimized mechanical engagement. Its aerodynamic, tapered profile is designed to facilitate smooth, low-friction connection with tulip contacts, ensuring long-term operational stability and reduced wear. This robust contact arm provides exceptional thermal resistance and reliable power transmission for critical electrical distribution infrastructure.
