Circuit Breakers are electric devices used to automatically interrupt an electric circuit in the event of an overload or a short circuit, protecting it from damage caused by an excessive current.The 219-3-21242-8 is a miniature circuit breaker from the 9 A range of products from Barrow. It is designed to provide protection against overloads, short circuits and overloads with protection also for ground fault currents.

This circuit breaker can be used in a variety of applications, from small DC power circuits to larger industrial AC networks. In DC power applications, the breaker is used to protect against overloads or short circuits, while in AC networks, the breaker can be used to protect against possible phase or ground faults. In either case, the breaker is designed to protect the circuit from damage from excessive current.

The 219-3-21242-8 circuit breaker is designed to trip when a circuit experiences an increased current greater than the rated capacity of the breaker. Once the breaker trips, the circuit is automatically shut off and the circuit protected from further damage.

The working principle of the 219-3-21242-8 circuit breaker is basically the same as any other circuit breaker: when the current exceeds the limit of the breaker, it trips and automatically shuts off the circuit. The breaker is triggered if the current exceeds the rated value (eg 10A), and the breaker can also be manually reset. It is important to note that the breaker may not necessarily shut off the current when it trips – rather it simply interrupts the flow of current, thus protecting the circuit from further damage.

The 219-3-21242-8 circuit breaker is an economical and efficient way to protect electrical circuits. It is designed to provide reliable protection against overloads, short circuits and ground faults. This type of circuit breaker is widely used in both residential and commercial applications, ensuring the safety of electrical circuits and protecting them from possible damage.
