← TechnologyWhich outcome accelerates when a circuit breaker repeatedly trips because of inductive load switching?
A)Arc chute aging from plasma erosion✓
B)Contact welding from inrush current
C)Insulation degradation from voltage spikes
D)Mechanism failure from mechanical stress
💡 Explanation
When a circuit breaker repeatedly trips due to inductive load switching, arc erosion of the arc chute occurs because the plasma generated with each break degrades the insulating material. Therefore, arc chute aging accelerates rapidly, rather than welding, insulation breakdown, or mechanism failure, which arise from different causes and time scales.
