Circuit breakers are a critical component in virtually all electrical systems. Their purpose is to provide a way to quickly and safely interrupt a short circuit or overload, thereby protecting both your equipment and your wiring. The LELK1-1REC4-31735-1-V is an example of a circuit breaker, and this article will explore its application field and working principle.

This breaker is a three-phase, type AC1/AC3 system breaker designed for three-phase, alternating current systems. It has a rated voltage of AC 380/220V and a rated operating current of 40A. It also has a rated frequency of 50/60Hz and a rated insulation voltage of AC 380V. This circuit breaker is suitable for use in commercial and industrial applications, as well as in residential buildings.

The working principle of the LELK1-1REC4-31735-1-V is simple. When connected to the electrical system, it monitors the system for any sudden changes in current, or a short circuit or overload. In the event of either of these occurrences, it will immediately open the circuit, and thereby protect the system. The circuit breaker has an adjustable thermal sensitivity, so it can be adjusted to suit the particular application.

This particular breaker features several features that make it suitable for a wide variety of applications. For instance, it has a high breaking capacity (up to 10 times its rated current) and it is short-circuit current-limiting. This can help to provide protection in the event of a short circuit, as the breaker will limit the current to a safe level. Another feature is the built-in thermal protection, which helps to provide further protection from overheating. This helps to ensure that the breaker remains reliable even under heavy load conditions.

The LELK1-1REC4-31735-1-V is also available with an optional control unit. This unit allows for the breaker to be connected remotely and controlled from a distance. This can be useful for instance, if the circuit breaker needs to be activated or deactivated from a remote location. This can help make maintenance work more efficient by allowing for the breaker to be adjusted without having to be physically present.

In conclusion, the LELK1-1REC4-31735-1-V is a three-phase, type AC1/AC3 system breaker designed for three-phase, alternating current systems. It has a rated voltage of AC 380/220V and a rated operating current of 40A. The breaker has several features that make it suitable for commercial and industrial applications, as well as in residential buildings. It has a high breaking capacity and a built-in thermal protection, which provides reliable protection even under heavy load conditions. The breaker can be connected to a control unit for remote activation or deactivation, making it more efficient for maintenance work.
