A circuit breaker is an automatic switch used for controlling and protecting electric systems from damage caused by overloads. Circuit breakers are designed to be able to detect an overload or short-circuit condition and then open the circuit to protect the equipment from any further damage due to the fault. Circuit breakers can also be used to isolate parts of an electrical system or in the case of a major fault, to disconnect the whole system. The application field of circuit breakers is vast, they are used in a wide variety of applications from residential homes to large industrial installations.

The 219-3-7495-1 circuit breaker is a type of 3-pole, 50 Amp circuit breaker with a 12 kA tripping current rating. It is typically used for single-phase applications, either in buildings, schools, or industrial sites. This type of breaker has a longer tripping time than most standard breakers making it more suitable for use in large installations. This makes it ideal for applications where long distance runs are needed such as in large commercial offices where there is a need for many electrical outlets in different areas.

The working principle of the breaker is fairly straightforward. When an electrical load is placed on the circuit, the device monitors the current flowing through it. If this current reaches a pre-set limit for a certain amount of time, the breaker will then automatically trip and open the circuit. Generally, the tripping mechanism has a thermal element that applies a mechanical force to the contact trip bar in order to open the circuit. Once the breaker trips, it will remain in the open position until the overcurrent conditions are cleared and the reset button can be pressed to close the circuit again.

Overall, the 219-3-7495-1 circuit breaker provides a reliable and robust solution for applications with medium to high current requirements. Its robust design allows it to withstand current overloads, while its tripping characteristics ensure that it is suitable for a range of applications. The breaker also provides excellent protection for the system from any damage caused by power surges.
