LELPK11-1REC4-32289-1-V Circuit Protection

Circuit breakers are devices that rapidly de-energize electrical circuits to prevent motor or system overloads. Circuit breakers can be employed in a variety of applications, ranging from household and para-professional electricians to large industrial applications. The LELPK11-1REC4-32289-1-V is one such device, and its application field and working principles will be discussed in this article.

The LELPK11-1REC4-32289-1-V is a motorized break-away switch. It is typically deployed in large industrial and commercial environments, where it is used to protect electrical systems from overloads and sudden spikes in power demand. Its key feature is its ability to break away quickly from the main circuit in order to shield the system from any potentially damaging overloads or spikes. This helps ensure that safety is maintained and system components are kept running optimized for a longer period of time.

This protection is provided by the principle of a ‘bimetallic thermometer’. The device is designed to detect excessive heat that could be generated due to an overload or a spike in the system. The LELPK11-1REC4-32289-1-V employs a bimetallic strip that is heated by any excess current, while simultaneously increasing the tension in the strip. This results in the strip breaking, which in turn trips the circuit breaker and disconnects the circuit from the power supply. This trips the contacts of the breaker open and signals a visual and audible indication to alert any personnel in the area.

The LELPK11-1REC4-32289-1-V also includes additional features that help improve the safety and performance of the device. These include differential protection – a system which is designed to compare the power apparent on both sides of the break-away switch, allowing it to accurately detect excess temperature in the system. Additionally, the LELPK11-1REC4-32289-1-V also includes external warning contacts, enabling an additional level of protection by providing a further warning of potential overloads or spikes in the system.

The LELPK11-1REC4-32289-1-V is a reliable and cost-effective device for protecting industrial and commercial electrical systems. Its key benefit is the ability to quickly de-energize circuits to protect motors or systems from overloads or spikes. This is achieved by employing a bimetallic thermometer in order to detect excess heat in the system, while also providing additional features such as differential protection and external warning contacts for improved safety and performance.
