Introduction:
The breaking capacity and making capacity are important specifications of a circuit breaker. They describe the ability of the circuit breaker to interrupt a fault current and make or close a circuit, respectively. The breaking capacity refers to the maximum fault current that the circuit breaker can safely interrupt without causing any damage. On the other hand, the making capacity refers to the maximum current that the circuit breaker can safely close and carry without causing any damage.
Explanation:
The making capacity of a circuit breaker should be more than its breaking capacity. This is because during the closing operation of a circuit breaker, there is a high inrush current that flows for a short duration. The inrush current is an instantaneous surge of current that occurs when the circuit is closed and the electrical load is connected to the power source.
Reasoning:
1. Inrush current: When the circuit breaker is closed, the inrush current can be significantly higher than the normal operating current. This is because the electrical load connected to the circuit may have capacitive or inductive characteristics that cause a transient surge in current.
2. Mechanical stress: The inrush current can create mechanical stress on the circuit breaker's contacts and other components. If the making capacity of the circuit breaker is not sufficient, it may lead to excessive heating and damage to the contacts, resulting in their failure.
3. Arcing: In addition to mechanical stress, the inrush current can also cause arcing between the contacts of the circuit breaker. Arcing can generate high temperatures and cause damage to the contacts and insulation materials.
4. Safety and reliability: By having a making capacity that is higher than the breaking capacity, the circuit breaker can safely close and carry the inrush current without any damage or failure. This ensures the safety and reliability of the circuit breaker and the electrical system it protects.
Conclusion:
In conclusion, the making capacity of a circuit breaker should be more than its breaking capacity. This is necessary to safely close and carry the inrush current without causing any damage or failure to the circuit breaker and the electrical system.
