Circuit Breakers

CMB-043-11-C-3-N-B-A Application Field and Working Principle

Circuit breakers play an important role in the electrical system, providing overcurrent protection in case of a dangerous electrical fault. The CMB-043-11-C-3-N-B-A is a specific type of circuit breaker. It is an oil-immersed circuit breaker, primarily used in high voltage power distribution systems. It features advanced oil cooling technology and a vacuum interrupter, allowing it to handle large amounts of current without damage.

Application Field

The CMB-043-11-C-3-N-B-A circuit breaker is mainly used for high-voltage power distribution systems, with a rated voltage of 40.5 KV. It is mainly used for the protection of power distribution systems, but it can also be used for motor overload protection, short-circuit protection and other overcurrent protection applications.

Working Principle

The CMB-043-11-C-3-N-B-A circuit breaker uses an advanced oil cooling system to ensure a safe and consistent current flow. When a current spike occurs, the circuit breaker can detect it within a few milliseconds, and will open the circuit to protect against possible damage. This is done by using a set of contacts, which close when the current is below the maximum threshold, and open when the current exceeds the threshold. The contacts are connected to an oil filled tank, which dampens the electric arc that would otherwise be produced when the current is interrupted.

The CMB-043-11-C-3-N-B-A circuit breaker also uses a vacuum interrupter to prevent large faults from damaging the power distribution system. The interrupter is activated when a large fault occurs, producing a high voltage spark that arcs across the contacts, disrupting the power flow. This reduces the chance of power surges, which can cause extensive damage to electric equipment.

Additionally, the CMB-043-11-C-3-N-B-A circuit breaker also contains a trip mechanism, which can detect abnormal electrical activity. The trip mechanism is sensitive to high voltage spikes and power surges, and will automatically open the circuit whenever it detects a potentially dangerous fault. This provides a further layer of protection for the power distribution system.

Conclusion

The CMB-043-11-C-3-N-B-A circuit breaker is an important component of high voltage power distribution systems, providing protection against electrical faults and surges. It features advanced oil cooling technology and a vacuum interrupter, allowing it to handle large amounts of current without damage. Additionally, it also contains a trip mechanism, which can detect abnormal electrical activity and automatically open the circuit whenever it detects a potentially dangerous fault. Overall, the CMB-043-11-C-3-N-B-A circuit breaker is a reliable and versatile device, providing a high level of protection for power distribution systems.
