Circuit Breakers are essential elements in multiple electricity driven systems, enabling electricity to be swiftly cut off when overheating, overload, or other damage is sensed. The LELBX11-34019-15-V is a specific form of circuit breaker which is ideal for certain applications. In this article, we will discuss the application field and working principle of the LELBX11-34019-15-V.

The LELBX11-34019-15-V is most often used in industrial circuits, and is available in many different sizes and amperages for voltage ratings ranging from 15 to 240 volts. It also features a built-in thermal-magnetic trip element and an adjustable instantaneous pick-up. The adjustable current rating of the trip device makes it ideal for industrial applications where current variations may occur. Additionally, a momentary triple push-button test switch allows accurate current level settings and testing during commissioning and system maintenance.

The LELBX11-34019-15-V utilizes a special thermal-magnetic trip element, comprised of a thermal trip arm and a bimetallic strip. The strip is heated by the current passing through the circuit, and expands when the temperature rises. The thermal arm is connected to the bimetallic strip, and acts as a toggle switch in order to trip the circuit breaker when the set temperature has been reached.

In addition, the device contains a magnetic trip element. This element functions in a similar manner to the thermal-magnetic trips found in fuses, but instead uses an electromagnet. When the threshold amount of current is exceeded, the magnet creates a magnetic field that activates a latch, resulting in the locking of the circuit breaker and cutting power to the circuit.

In addition to its primary functions, the LELBX11-34019-15-V offers several safety features. Its trip mechanism is designed to open and close only when the current passes in one direction, meaning it can only be manually reset after a trip. Additionally, the current-limiting feature helps reduce current transients in the event of overloads or short circuits, further protecting the circuit from damage.

In summary, the LELBX11-34019-15-V is a specialized circuit breaker designed for industrial applications. It utilizes a thermal-magnetic trip element with adjustable current rating, as well as a momentary triple push-button test switch. Additionally, it offers several safety features, including current limitation and trip mechanism which only opens and shakes when the current flows in one direction.
