219-3-7340-34

Circuit breakers form the cornerstone of a reliable and safe electrical system and are vital components of any electrical distribution and protection system. The 219-3-7340-34 circuit breaker is an especially important model that is specified for use in the protection of low voltage distribution systems, and is also approved for use in industrial, healthcare and mining applications. In this article, we will discuss the 219-3-7340-34 circuit breaker’s main application fields, as well as the operating principles on which it relies for its functioning.

Application Field

The 219-3-7340-34 is only suitable for direct current applications, and it is mainly deployed for the protection of low voltage circuits in branch, switchboard and other types of distribution systems. This circuit breaker is approved for use in both indoor and outdoor circumstances, even in locations where high levels of humidity are present. Additional applications come in the form of industrial, mining and healthcare settings, and this circuit breaker is even often specified for use in the protection and control of lighting circuits. All in all, the 219-3-7340-34 provides a great level of flexibility in terms of its application field.

Working Principle

The 219-3-7340-34 circuit breaker is a direct current-specific device that is based on a thermal-magnetic operating principle. As such, it is equipped with an array of features, such as a thermal component, which is the main operating element, as well as other elements such as a switch and a time-delay fuse. The thermal component triggers the switching of the circuit breaker when it is exposed to both heat and voltage for an extended period of time. The switch then turns the circuit breaker on or off, depending on its programming, while the time-delay fuse provides time-delay protection in the event of a fault. When the thermal component is heated up to its prescribed level, it causes the switch to activate and the circuit breaker to turn off.

In addition to its thermal-magnetic operating principle, the 219-3-7340-34 also has a range of other features, such as a manual reset button, automatic reset button, and a “trip indication” light. The manual reset button allows operators to reset the circuit breaker manually whenever necessary, while the automatic reset button ensures that the breaker will reset itself in the event of a fault. Finally, the “trip indication” light acts as a visual indication of when the circuit breaker has been tripped.

Overall, the 219-3-7340-34 circuit breaker is an especially important model that has been designed for use in a variety of applications. Thanks to its thermal-magnetic operating principle, it provides a reliable and safe level of protection for equipment and personnel both on-site and off-site. It can be used in indoor and outdoor settings, as well as in industrial, healthcare and mining applications, and is known for its flexibility and reliability.
