Circuit breakers are a major component of electric systems, mainly used for overload, short circuit protection and control. The LELBXK1-39011-70-V circuit breaker is a common product of this type, providing a wide range of applications in prospective short-circuit and overload current protection, as well as in normal switching of all types of circuits for a range of electrical and control systems. The following article will discuss the LELBXK1-39011-70-V application field and working principle in detail.

The LELBXK1-39011-70-V circuit breaker includes specialized automatic switchgear that allow personnel to safely work on and operate the device by preventing electric shock and other types of electrical hazards. This type of breaker is mainly used in low-voltage distribution systems, typically rated up to 400 amperes and 600 volts, making them ideal for applications involving standard household appliances. The LELBXK1-39011-70-V circuit breaker also includes insulation monitoring, arc-fault detection and protection, and overload and short-circuit protection built into the device.

The working principle of a LELBXK1-39011-70-V circuit breaker is similar to a standard breaker but is designed to handle higher levels of current. It works by sensing the overcurrent or short-circuit conditions and quickly shutting off the circuit to prevent further damage or harm. This type of breaker consists of two main components, the main contacts and the trip unit. The main contacts connect the incoming power to the load, while the trip unit monitors the current in the circuit and trips the breaker when a fault is detected.

The LELBXK1-39011-70-V circuit breaker may also provide delayed protection, which allows the breaker to temporarily remain on while the trip unit detects a fault. This feature gives engineers more time to recover before an especially dangerous overload occurs. Delayed protection is especially important in situations where overload protection is required without immediately cutting off all power.

The LELBXK1-39011-70-V circuit breaker is also equipped with an overcurrent protection feature, which is designed to shut off the power in the event of an unusually high current. This feature can be especially useful in preventing fires caused by overloaded circuits. Finally, the device’s insulation monitoring system continuously checks the insulation of the circuit to ensure that it is safe and properly insulated.

In conclusion, the LELBXK1-39011-70-V circuit breaker is designed for use in low-voltage systems and provides prospective short-circuit and overload current protection as well as normal switching of all types of circuits in electrical and control systems. This type of breaker is equipped with a variety of features, such as delayed protection, overcurrent protection, and insulation monitoring, that make it well-suited for its applications.
