Arc runner contacts are critical components in circuit breaker arc chutes that guide and extinguish electrical arcs during fault interruption.
Arc runner contacts are specialized conductive elements within circuit breaker arc chutes designed to capture, guide, and facilitate the extinction of electrical arcs generated during circuit interruption. These components work in conjunction with arc plates and chutes to rapidly elongate, cool, and deionize the arc plasma, preventing equipment damage and ensuring safe operation. They are engineered to withstand extreme thermal and electromagnetic stresses during fault conditions.

To capture and guide electrical arcs into the arc chute structure where they can be safely extinguished through elongation, splitting, and cooling.
Copper-tungsten combines excellent thermal conductivity (copper) with high melting point and arc erosion resistance (tungsten), making it ideal for withstanding extreme arc temperatures.
They ensure rapid and reliable arc extinction, preventing sustained arcing that could cause equipment damage, fires, or electrical system failures.
