The correct answer is: recovery voltage.
Recovery voltage is the voltage that appears across the contacts of a circuit breaker after they have opened. It is caused by the inductance of the circuit, which tries to keep the current flowing even after the contacts have opened. The recovery voltage can be very high, and it can cause the circuit breaker to arc over. To prevent this, circuit breakers have arc suppression devices that help to extinguish the arc.
Surge voltage is a sudden increase in voltage that can occur due to a number of factors, such as lightning strikes or switching operations. Surge voltages can damage equipment and cause power outages. Surge protectors can be used to protect equipment from surge voltages.
Operating voltage is the voltage that a circuit breaker is designed to interrupt. The operating voltage must be higher than the maximum voltage that the circuit breaker will be exposed to in order to ensure that the circuit breaker will open safely.
Arc voltage is the voltage that is required to maintain an arc between the contacts of a circuit breaker. Arcing can cause damage to the circuit breaker and can also create a fire hazard. Circuit breakers have arc suppression devices that help to extinguish the arc.
None of the above is not a correct answer.
