Which outcome is most likely if inductive load switching causes exceeding voltage transients across a circuit breaker’s contacts?

💡 Explanation

When switching inductive loads, exceeding voltage transients can cause dielectric breakdown as insulation is unable to withstand surges. Restrike occurs as the breaker attempts to interrupt. Therefore arc restrike is most likely, exceeding mechanical trip wear, core losses, or insulation heating, which have alternative causes.
