Circuit breakers are designed to protect electrical systems such as machines, appliances, and tools from damage caused by electric overloads and short circuits. Circuit breakers can be identified by model numbers like LELZXPB11-1REC4-59-101.-AG2-03. This article will explain the application fields and working principle of this particular model.

This circuit breaker is mainly used in residential and industrial environments, particularly for 220/240V AC single phase applications. It is typically used to protect circuits by cutting off the power when a fault is detected. The circuit breaker also plays a vital role in the prevention and reduction of electrical fires.

This specific circuit breaker works by sensing current in the circuit. If the current reaches a critical level, indicating an overload or short circuit, the breaker will quickly disconnect the circuit and prevent it from being energized. This releases the heat that can produce during an electrical fault, which helps to reduce the risk of fires.

This circuit breaker uses a magnetic current sensing device, along with a thermal component, to detect an overcurrent condition. When an overload or short circuit occurs, the sensing device sends a signal to the thermal component. This in turn trips the contacts, which opens the circuit and disconnects the power.

When the fault is resolved, the circuit breaker can be reset by pressing the reset button or operating the toggle switch. This will close the contacts and allow the current to flow again. The circuit breaker will automatically reset itself if the fault is cleared before the contacts open.

The circuit breaker also has a secondary function known as a ground fault interrupter. This device monitors the current going into and out of the ground, and if it detects an imbalance, indicating a potential ground fault, it will interrupt the circuit and prevent any potential damage.

In conclusion, the LELZXPB11-1REC4-59-101.-AG2-03 circuit breaker is a reliable device used to protect electrical systems from overcurrents and short circuits. It works by sensing current in the circuit and then quickly disconnecting it when a fault is detected. The circuit breaker has a secondary function of ground fault interrupter, which helps to detect and prevent ground faults. This circuit breaker is typically used in residential and industrial applications, but can be used in a wide variety of other circumstances as well.
