Arc runners are conductive components in arc chutes that guide and extinguish electrical arcs during circuit breaker operation.
Arc runners are metallic or conductive elements strategically positioned within an arc chute assembly of circuit breakers or switches. Their primary function is to attract, split, and guide the electrical arc formed during contact separation away from the main contacts, directing it into the arc chute's quenching chamber where it is cooled, elongated, and extinguished through deionization and cooling mechanisms. This prevents contact erosion, maintains dielectric strength, and ensures safe interruption of fault currents.

Arc runners guide the electrical arc away from the main contacts into the arc chute, where it is split, cooled, and extinguished to prevent damage and ensure safe current interruption.
They reduce contact erosion, enhance arc extinction efficiency, increase interrupting capacity, and extend the operational lifespan of the circuit breaker by managing arc energy effectively.
Typically, arc runners are integrated into the arc chute assembly and may require replacement of the entire chute or specific sections, depending on design and wear assessment.
