Circuit breakers are devices used to de-energize or disconnect a circuit or component due to an overload, electrical short-circuit, or any other power anomaly. The LEL1-1RS4-51-30.0-AL-01-V is a sophisticated, three-phase circuit breaker used in industrial buildings and systems. In this article, we’ll take a look at the LEL1-1RS4-51-30.0-AL-01-V’s application field and working principle.

Application Field

The LEL1-1RS4-51-30.0-AL-01-V circuit breaker is designed to handle the load present in three-phase systems. It is a Type A, rated for 480 Volts AC and 65kA at 240 volts. With this breaker, you can install multiple power systems in one unit. It is also designed to handle various external influences, such as short circuits, line voltage surges, and external noise. Additionally, the breaker can be used as a main breaker or sub-circuit breaker.

It is ideal for industrial applications, such as in factories and power stations. The size and design of the breaker make it a great choice for these large-scale electrical systems. In addition, the LEL1-1RS4-51-30.0-AL-01-V can be used in medical and recreational facilities, such as restaurants, theaters, and swimming pools. The breaker has been tested and approved to meet various safety and quality standards.

Working Principle

The LEL1-1RS4-51-30.0-AL-01-V utilizes an electromechanical mechanism to disconnect the circuit in the event of an overload or electrical fault. This is accomplished by an internal mechanism that detects an increase in current and triggers the opening of the breaker’s contacts. In the normal on position, the contacts remain closed, allowing the electrical current to flow freely. When the current exceeds the breaker’s rated capacity, the contacts are opened, which interrupts the current flow, thus preventing damage to the system.

The LEL1-1RS4-51-30.0-AL-01-V also has a manual override feature. This feature allows the breaker to be manually reset if there is no danger of a short circuit occurring. This feature also allows for quick resetting of the breaker if it became necessary to do so.

In addition to the internal mechanism, the LEL1-1RS4-51-30.0-AL-01-V also utilizes various external protection mechanisms. For example, it has thermal protection, which shuts off the breaker’s contacts if the temperature inside the breaker exceeds a certain limit. The breaker also has current protection, which shuts off the breaker’s contacts in the event of an overload or short circuit. Lastly, it also has a ground fault protection, which shuts off the breaker’s contacts if there is an electrical fault or surge that might damage the system.

Conclusion

The LEL1-1RS4-51-30.0-AL-01-V is a top-of-the-line three-phase circuit breaker. It is designed to handle a variety of load conditions and external influences. It also has several protection mechanisms, such as thermal protection, current protection, and ground fault protection. With its sophisticated design and proven quality, the LEL1-1RS4-51-30.0-AL-01-V is an ideal choice for industrial, medical, and recreational applications.
