← TechnologyWhich operational challenge arises when a circuit breaker interrupts a highly inductive AC load?
A)Arc restrike due to voltage transient✓
B)Overheating from reverse current flow
C)Contact welding from inrush current
D)Reduced lifespan from mechanical stress
💡 Explanation
When interrupting an inductive load, a voltage transient is generated by the collapsing magnetic field which can cause arc restrike across the breaker contacts as they separate because of high dV/dt. Therefore arc restrike occurs, rather than overheating, contact welding, or reduced lifespan, which arise from alternative system stresses.
