Circuit breakers are devices designed to protect electrical systems, electronic components and circuitry from damage caused by an overcurrent or short circuit. Circuit breakers are available in various types, configurations and features to provide flexible and reliable system protection. One such circuit breaker is the LELK1-1-52-5.00-01-V. This article will discuss the application field and working principle of this particular circuit breaker.

The LELK1-1-52-5.00-01-V is a low voltage, 23A AC circuit breaker. It is designed for the protection of single phase and three phase distribution systems up to a power rating of 230VAC. This includes protection for low voltage overhead networks, such as transformers and motors, as well as residential and commercial circuits. Additionally, the LELK1-1-52-5.00-01-V can be used as a main switch or as a branch fuse holder.

The LELK1-1-52-5.00-01-V incorporates two main components: the main circuit element and the auxiliary release mechanism. The main circuit element is a split-phase, bimetallic thermal element that has been designed to respond quickly to electrical faults. The thermal elements are designed to detect increases in current that exceed the rating of the breaker, such as those caused by electrical overloads, short circuits and ground faults. When an overload or fault is detected, the thermal element will respond by connecting the contacts together, thus interrupting the circuit and protecting against damage. An auxiliary release mechanism is incorporated to provide an additional source of protection. This release mechanism is designed to be triggered by manual control or by a signaling device connected to the circuit, allowing it to respond to faults that are outside the range of the main circuit element.

The LELK1-1-52-5.00-01-V also provides additional safety features. The impedance of the circuit breaker can be adjusted via the auxiliary release mechanism, allowing for more precise control over the maximum current in the circuit. Additionally, a time delay can be selected to prevent the breaker from tripping in response to momentary overloads. The breaker can also be configured to operate as a single pole or double pole circuit breaker, providing extra protection in case of a high-power fault.

In summary, the LELK1-1-52-5.00-01-V is an AC circuit breaker that provides reliable system protection for low voltage applications up to 230VAC. It incorporates a bimetallic thermal element and an auxiliary release mechanism to detect and respond to electrical faults. The breaker also provides additional safety features such as adjustable impedance and delayed tripping to provide extra protection.
