Circuit Breaker as a switch device that can switch on, carry and break the current under normal circuit conditions, and can also switch on and carry a certain time and break the current under specified abnormal circuit conditions, is an indispensable part of the power system. Its main function is to turn on, carry and break current under normal or abnormal loop conditions. This switching device can automatically cut off the circuit within a specified time to prevent equipment damage or fire caused by circuit overload, short circuit, undervoltage and other faults. The circuit breaker combines the functions of the fuse switch and the over-under-heat relay, which can act quickly when abnormal current is detected to protect the safety of the circuit and electrical equipment.
Application
As an important protection equipment in the power system, the circuit breaker not only ensures the stable operation of the power grid, but also protects the safety of the circuit and electrical equipment. In addition, circuit breakers also play a very critical role in other areas, such as in building electrical systems, used to protect circuits and electrical equipment from current overload; In industrial equipment, it is used to control various motors and electrical equipment on the production line to ensure that the equipment is protected during normal operation, and at the same time, the power is quickly cut off in the event of failure to prevent equipment damage and production interruption; With the development of smart grids and renewable energy, circuit breakers are constantly evolving. The intelligent circuit breaker integrates electronic technology and communication technology, which can realize remote control and monitoring, and improve the intelligent level of the power system. In microgrid, solar photovoltaic and other fields, solid circuit breakers have been widely used because of their environmental protection, miniaturization and high reliability.
FAQ about Circuit Breakers
-
1. How does a circuit breaker work?
A circuit breaker monitors the current in the circuit. When the current exceeds a preset safety value (usually an overload or short circuit), the circuit breaker will automatically trip and cut off the current to protect the circuit from damage.
-
2. What types of circuit breakers are there?
Common types of circuit breakers include:
Miniature circuit breaker (MCB)
Residual current circuit breaker (RCD/RCBO)
Air circuit breaker (ACB)
Molded circuit breaker (MCCB)
Vacuum circuit breaker (VCB)
-
3. What is the difference between a molded case circuit breaker (MCCB) and a miniature circuit breaker (MCB)?
MCCBs are used for higher current applications, with rated currents up to 1000A or even higher, and are suitable for industrial environments; while MCBs are suitable for smaller current loads and are generally used in home and small commercial applications.
