The reason to use a medium voltage circuit breaker is simple, your systems requirements is the reason. In order to properly protect your and maintain your equipment it makes sense for you to implement the correct protection. Most low voltage circuit breakers are designed to handle voltages of 1kV or lower. On the other hand, the medium voltage circuit breaker range typically covers from 1kV to 72.5 kV.

Here is a list of reasons that circuit breakers are a necessity in the electrical industry:

1. Protection of Equipment: Circuit breakers are crucial for protecting electrical equipment from damage due to overcurrent, short circuits, and other electrical faults. They interrupt the flow of current when abnormal conditions occur, preventing damage to transformers, generators, motors, and other high-value equipment.
2. Safety: Circuit breakers help ensure the safety of personnel working with or near electrical equipment. They isolate faulty sections of the electrical system, reducing the risk of electric shock and fire hazards.
3. Reliability: Medium voltage circuit breakers contribute to the overall reliability of electrical systems by minimizing downtime. When faults occur, circuit breakers can quickly isolate the affected area, allowing the rest of the system to continue operating normally.
4. Regulatory Compliance: Electrical codes and standards often require the use of circuit breakers in medium voltage applications to ensure compliance with safety regulations and guidelines. Installing circuit breakers helps meet these regulatory requirements.
5. Remote Operation and Monitoring: Many modern medium voltage circuit breakers are equipped with remote operation and monitoring capabilities. This allows for easier control of the electrical system and facilitates proactive maintenance, reducing the risk of unexpected failures.
6. Fault Isolation: In the event of a fault, such as a short circuit, a circuit breaker can isolate the faulty section of the electrical system, preventing the fault from propagating to other parts of the system. This minimizes the extent of the outage and helps in troubleshooting and repairing the fault.
