Circuit breakers are essential components in various electrical systems, as they provide protection from dangerous levels of current. The LELK1-36171-2021-V is a type of circuit breaker designed for use in a variety of applications. This article will take a look at the application field and working principle of this circuit breaker to help provide a better understanding of how it works.

The LELK1-36171-2021-V is an AC circuit breaker that is used to protect electrical components from being damaged by too much current. It is capable of interrupting flows of current up to 3617A, making it suitable for use in a wide variety of applications. It is widely used in industrial, commercial, and residential settings, where it is used to provide safe protection against short-circuits and overloads. The LELK1-36171-2021-V is also designed for use in more extreme applications such as photovoltaic systems, which require circuit breakers that are able to withstand excessive currents and prolonged cycles.

The LELK1-36171-2021-V works by using a bimetallic strip to detect when excessive current is entering an electrical system. The bimetallic strip is made of two different types of metal that have different thermal expansion properties. When current passes through the bimetallic strip, it causes the two metals to expand at different rates. This expansion causes the bimetallic strip to bend, which trips a mechanism in the device. The mechanism then causes the LELK1-36171-2021-V to open in order to protect the electrical components from damage.

The LELK1-36171-2021-V also features a thermal-magnetic unit that is designed to detect and trip the circuit breaker in the event of an excessive current. The thermal-magnetic unit consists of two components: the thermal element and the magnetic element. The thermal element generates heat when current passes through it. If the heat generated by the thermal element exceeds a pre-set temperature, then the magnetic element will trip the switch, causing the breaker to open.

The LELK1-36171-2021-V also has a number of safety features that are designed to ensure that the breaker continues to operate safely. These safety features include overload protection, short circuit protection, and lockout/tagout protection. The overload protection prevents the breaker from being overloaded, while the short circuit protection prevents it from tripping due to excessive current. The lockout/tagout protection ensures that the breaker is locked in the off position so that it cannot be operated until the lockout is released. This prevents any unauthorized access to the electrical system.

Overall, the LELK1-36171-2021-V is a reliable Circuit Breaker that is designed for use in a variety of applications. It is capable of interrupting flows of current up to 3617A, making it suitable for use in industrial, commercial, and residential settings. It features a bimetallic strip, thermal-magnetic unit, and a variety of safety features that provide reliable protection from dangerous levels of current. By understanding the application field and working principle of the LELK1-36171-2021-V circuit breaker, users can be sure to get the most out of this reliable and safe device.
