Circuit breakers play an important role in controlling and protecting electrical circuits by interrupting current flow. The LEL1-29869-2 circuit breaker is one such device, designed for indoor installation in low-voltage applications to protect control and distribution circuits from overcurrents and short circuits.

A LEL1-29869-2 circuit breaker is composed of a contact system, an arc interruption chamber, and a tripping system.

The contact system of this type of breaker is composed of a fixed contact, a moving contact and a contact carrier, usually made of steel. The stationary contact is mounted on the breaker\'s inner wall, while the moving contact is tightly connected to the contact carrier. When the circuit is closed, the two contacts are in contact and allow current to flow, while when the circuit is opened or tripped due to an overcurrent or short-circuit, the two contacts separate and the current is interrupted.

The arc interruption chamber of the LEL1-29869-2 circuit breaker is an enclosed chamber surrounded by an insulating material like vacuum or air. It is connected to the moving contact of the contact system and serves to interrupt an electric arc formed when the circuit is opened. The arc is terminated by cooling it with the flowing air or vacuum in the chamber.

The tripping system of this type of circuit breaker is designed to detect when an overcurrent or short-circuit occurs in the circuit and trip the circuit breaker, thus interrupting the current flow. It may be a thermal, magnetic or electronic type, depending on the application.

The LEL1-29869-2 circuit breaker can be used in low-voltage applications like residential homes, commercial buildings, and industrial plants. It is used to protect the circuit against overload, short circuits, and other electrical disturbances.

Overall, the LEL1-29869-2 circuit breaker is a reliable and cost-effective device for protecting circuits in residential, commercial, and industrial applications. It is composed of a contact system, an arc interruption chamber, and a tripping system and is designed to detect and interrupt current flow in the event of an overcurrent or short circuit.
