Circuit Breakers are an integral part of modern electrical systems and come in a variety of designs and sizes. The LELBXB1-1RS4-38434-15 circuit breaker is among the most popular, due to its wide range of applications and its ability to provide reliable service. It is a single-pole, triple-pole circuit breaker, with three-pole thermal and magnetic protection.

This particular circuit breaker is ideally suited for both low voltage and medium voltage applications, such as domestic wiring, lighting, refrigerators, air conditioners, electric ovens and motors. Its rated current is 100A, making it suitable for applications up to three-phase 400V.

The LELBXB1-1RS4-38434-15 circuit breaker consists of a main trip unit, which consists of a contact chamber, a main contact bar and trip setting device. It is equipped with a contact chamber cover and a handle, which is used to reset the trip setting device when necessary. The main contact bar is connected to the trip setting device, which is triggered when the current reaches a pre-set value.

The circuit breaker features thermal and magnetic protection. Thermal protection is provided by the contact chamber that is filled with a thermal resistant material, such as polyurethane foam. If the current exceeds the pre-set value, the polyurethane foam expands and pushes the contact chamber cover, which shuts off the circuit breaker.

Magnetic protection is provided by the main contact bar, which is connected to the trip setting device. If the current reaches a pre-set value, the trip setting device is triggered and the contact bar is pushed away from its original position, which shorts the circuit.

The LELBXB1-1RS4-38434-15 circuit breaker is also equipped with an adjustable overload and short circuit indicator, which signals when the current exceeds the pre-set value. It also has a mechanical locking mechanism to prevent resetting of the trip setting device when it is not necessary.

The LELBXB1-1RS4-38434-15 circuit breaker is designed to provide reliable service, even in challenging conditions. Its high quality components and construction ensure a long life and reliable performance. It is easy to install and requires minimal maintenance, making it a popular choice for use in complex electrical systems.
