Circuit breakers are protective devices designed to switch circuits off in the event of electrical overload or short circuit. The R11-4-2.90A-B06EV circuit breaker is a particular type of circuit breaker used for industrial and domestic applications. This article explains the application field and working principle of the R11-4-2.90A-B06EV.

Application Field

The R11-4-2.90A-B06EV circuit breaker is a specialized type of circuit breaker used specifically for applications that require high power loads. Its unique design allows it to be used in industrial, commercial, and domestic applications. The R11-4-2.90A-B06EV is particularly well suited for applications where high current needs to be safely dealt with and managed, including motor overloads and appliances drawing heavy current, such as kettles, irons, washing machines, and other large home appliances.

Working Principle

The working principle of the R11-4-2.90A-B06EV circuit breaker is based on a thermal-magnetic trip mechanism. The thermal element is made up of a bimetallic strip that senses heat generated in the circuit and expands, tripping the breaker. The magnetic element responds to high inrush currents, also tripping the breaker. The combined action of the thermal and magnetic elements provides high levels of protection for circuits. The combined action of the two elements ensures that the breaker will trip in the event of an overload, short circuit, or extreme inrush current.

The thermal element also provides additional protection against prolonged overloads. When current exceeds the rated limit of the breaker, the thermal element will gradually expand and trip the circuit. This provides additional safety in the form of programming a breaking point that is slow enough to prevent instant trip. The combined action of the thermal and magnetic elements ensures that the breaker will activate within an acceptable time period after the current exceeds the rated limit.

In addition to the thermal and magnetic elements, the R11-4-2.90A-B06EV circuit breaker also has a ground fault indicator that indicates if there is a ground fault in the system. It also includes an LED display that indicates the current state of the system. There are also selector switches for different settings.

Conclusion

The R11-4-2.90A-B06EV circuit breaker is a specialized type of circuit breaker designed for industrial and domestic applications that require high power loads. Its thermal and magnetic trip mechanism provides protection against overloads and short circuits. It also includes a ground fault indicator and LED display, as well as additional selector switches. The R11-4-2.90A-B06EV is a highly effective and reliable circuit breaker that provides high levels of safety in industrial and domestic applications.
