LELZXK1-1-52-100.-AG-03-V Circuit Protection

Circuit Breakers

Circuit breakers are electrical safety devices that protect electrical circuits from overloads and short circuits. Its main function is to prevent the flow of too much current, which can cause damage to wiring and other electrical components. The LELZXK1-1-52-100.-AG-03-V circuit breaker is an example of a type of circuit breaker designed to provide protection from a wide range of electrical hazards.

Application Field and Working Principle

The LELZXK1-1-52-100.-AG-03-V circuit breaker is suitable for use in low-voltage AC electrical power systems with a maximum working voltage of 500 V, a rated current of 30 A, and a rated breaking capacity of 10 kA. In addition, it is fully compliant with the IEC 61009-1 and EN 60898-1 international standards and certified with a UNI EN 61009-1 marking. It is also UL 1077 and CSA C22.2 listed.

The working principle of the circuit breaker is based on the phenomenon of arc extinction. When the circuit breaker is in the “on” position, current flows through the circuit. When the current rises to a level above the set breaking capacity, or very short time, the over-current protection of the circuit breaker will be triggered.

When triggered, the LELZXK1-1-52-100.-AG-03-V circuit breaker snaps open the contacts inside it, breaking the circuit and stopping the current flow. The circuit breaker is equipped with an internal arc extinguishing chamber, which works to reduce the contact gap and the internal arc quenching time. This helps to keep the arc within the arc chamber and prevents it from escaping, thus minimizing the risk of damage to the contacts.

In addition, the circuit breaker has a mechanical latching mechanism and double-break contact which allows it to maintain reliable contact performance, even after multiple switching cycles. The latching mechanism helps to ensure that the circuit is only opened when necessary, and the double-break contact permits the current to be instantly switched between the contacts.

The LELZXK1-1-52-100.-AG-03-V circuit breaker is designed for a wide range of applications, such as residences, small buildings, commercial and industrial buildings, and electrical and electronic systems. With its combination of features and performance, it is an ideal choice for those looking for protection against overloads and short circuits in their electrical systems.
