Circuit Breakers are electrical devices that are designed to help protect electrical systems from short circuits, over current, and other potentially damaging electrical conditions. The LELK12-1REC5-71166-20-G2-V circuit breaker is one such device. It is designed to provide reliable protection against electrical faults and overloads, and to automatically disconnect the power in the event of an overcurrent or wire failure.

The components of the LELK12-1REC5-71166-20-G2-V circuit breaker include a main service switch, trip switch, holding device, and contact system. The main service switch is used to either open or close the circuit breaker. The trip switch senses the current flow of the circuit and then trips the breaker if the current is too high. The holding device maintains the circuit breaker in the open or closed position, depending on the current passing through it. The contact system serves as the connection between the main service switch and trip switch.

The application field of the LELK12-1REC5-71166-20-G2-V circuit breaker is in medium-voltage electrical systems. This type of breaker is used in many different industrial, commercial, and residential applications. It provides reliable protection from both faults and overloads and helps to prevent equipment damage. It is also used in line-side power distribution and can be found in many machine applications, such as elevators, air conditioning equipment, and industrial machinery.

The working principle of the LELK12-1REC5-71166-20-G2-V circuit breaker is that it will automatically interrupt the power supply in the event of an overload or fault condition. The trip switch senses the current flowing through the circuit and then trips the breaker if the current is too high. If the current is at a normal level, the holding device will then keep the breaker in the closed position, allowing for uninterrupted power supply. In the event of an overload or short circuit, the main service switch automatically opens the breaker and the contact system then opens the circuit, thus preventing further damage.

In conclusion, the LELK12-1REC5-71166-20-G2-V circuit breaker is an effective device for protecting medium-voltage electrical systems. It has a main service switch, trip switch, holding device, and contact system to ensure reliable protection against faults and overloads. It is used in many different industrial, commercial, and residential applications and will automatically disconnect power in the event of an overcurrent or wire failure. This makes it an integral part of many electrical systems and an invaluable tool in helping to ensure the safety of both operators and equipment.
