Circuit breakers provide a critical safety function in the functioning of electrical systems. They are designed to quickly shut off electricity to reduce the potential danger of electrical shock and destruction of equipment. Knowing the application field and working principle of the LELK 11-39949-5-V circuit breaker is important in order to utilize it safely and effectively.

Application Field

The LELK 11-39949-5-V circuit breaker is designed for use in many different applications. It can be used in residential homes, commercial buildings, industrial settings and even electrical substations. The breaker is suitable for use in both AC and DC circuits and can accommodate both single-phase (alternating current) and three-phase (three-way alternating current) systems. Generally, it is used for both safety and power quality control in a variety of applications within different types of electrical systems.

Working Principle

The LELK 11-39949-5-V circuit breaker is designed to quickly disconnect the power supply from an electrical circuit when an overload or short circuit occurs. The breaker is designed to be highly responsive and will trip within a fraction of a second when an overdraft or excessive current is detected. The breaker utilizes a combination of thermal and electromagnetic means to quickly break the connection and prevent further damage to the system. Thermal sensing elements detect excessive temperature in the circuit and cause the breaker to trip. Electromagnetic forces are used to detect current anomalies that would indicate an overload or short circuit condition.

The circuit breaker also offers adjustable settings to allow it to be customized to the specific application. For example, the breaker common trip breaker (CBT) settings can be adjusted to adjust the trip level in order to meet the specific requirements of a given circuit. Additionally, the breaker can be equipped with a variety of accessories such as an auxiliary switch, meter, disconnect means, ground fault indicator, surge arrester and others.

The LELK 11-39949-5-V circuit breaker is a great choice for a wide range of applications due to its versatility, reliability and fast trip times. Knowing its application field and working principle is key to safely and effectively utilizing the breaker, and should be taken into consideration when selecting a breaker for a particular application.
