A circuit breaker is an electrical device designed to shut off power when current passes through it in an unsafe manner. Circuit breakers are typically used to protect equipment from overheating or short-circuiting. When this type of overload occurs, the breaker will shut off the power to prevent damage.

The LELHK111-1-63F-12.0-FK-01-V is a particular circuit breaker specifically designed for high AC current condition and high frequency operation. It is characterized by high breaking capacity, taking up a small area, and light weight features. It is applied in circuits where high inrush of AC current is necessary for the operation, such as large motors, highly inductive load, as well as heavily current changing load, and so on.

The working principle behind the LELHK111-1-63F-12.0-FK-01-V circuit breaker can be explained in three fundamental parts. First, when current passes through the circuit breaker, the contact of the breaker will open, and a small arc will be created between the contacts. Second, a magnetic field will then be created around the arc, which will serve to create a counteraction force against the spring tension. This will then cause the contacts to separate further, thereby preventing the flow of current. Lastly, the arc current releases energy in the form of ultraviolet radiation, which the arc chute from the breaker will absorb. In turn, this helps create cooling between the contacts, allowing them to become safely separated until the breaker is manually reset.

In summary, the LELHK111-1-63F-12.0-FK-01-V is a type of circuit breaker specifically designed to protect against high AC currents in high frequency environments, such as large motors or heavily changing currents. It works by cutting off current flow when a fault or overload occurs. It utilizes a magnetic counteraction force between its contacts and the circuit arc chute to separate them and effectively interrupt the current flow.
