Application:
- Overload Protection: MCCB is used to protect equipment and cables from overload, when the current exceeds the permissible limit for an extended period of time.
- Short Circuit Protection: MCCB breaks the circuit quickly when a short circuit occurs in the electrical system, preventing possible fires and fires.
- Ground Fault Protection: Some types of MCCBs have built-in leakage protection, helping to break the circuit when an electrical leak occurs, ensuring safety for people and property.
- Current control and regulation: MCCB can be used to control and regulate the current in the electrical system.
- Cut-off for electrical appliances: MCCB is used as an electrical switch to disconnect and connect current to electrical equipment such as machinery, motors, lamps, etc.
- Lightning protection: MCCB can be used to protect the system from the effects of lightning and create a protective layer for electrical equipment.
- Use in power distribution systems: MCCBs are used in main power distribution systems to cut off power when necessary to protect the entire system.
- Overvoltage Protection: Some MCCBs have built-in overvoltage protection, which prevents equipment and systems from unwanted pressure fluctuations.
