Circuit breakers are one of the most important elements of any electrical system. They provide protection against short circuiting, overloading, and other dangerous or damaging conditions. The LELB1-1REC4-39500-25-V is a type of circuit breaker that is designed to provide reliable, robust protection for a wide variety of applications and conditions.

Application Field

LELB1-1REC4-39500-25-V circuit breakers are designed for use in a range of applications, including residential and commercial buildings, factories, schools, data centers, airports, and other areas where high levels of electrical protection are required. These circuit breakers provide protection for wiring, outlets, lights, and other equipment from overloads, short circuits, and other electrical hazards. The LELB1-1REC4-39500-25-V circuit breaker is rated for a current rating of 25A, so it can be used to protect circuits that require up to this level of current, including most standard residential branch circuits. This circuit breaker also offers a high interrupting capacity of 39,500A, making it suitable for safeguarding against arcing faults, due to it being able to quickly disconnect power and prevent any further electrical damage.

Working Principle

The LELB1-1REC4-39500-25-V circuit breaker utilizes a process called thermal-magnetic tripping, to quickly and efficiently respond to dangerous electrical conditions. This process utilizes both thermal and magnetic elements, in conjunction with each other, to increase the accuracy and speed of shutdown. The thermal element is the primary response unit, as it is designed to sense electrical imbalances, like an overcurrent, and cause the circuit breaker to open almost immediately. The thermal element will cause the circuit breaker to trip in less than one-tenth of a second, ensuring that the circuit is disconnected quickly and safely. The magnetic element is used to sense more extreme imbalances, like short circuits and arc faults, and cause the circuit breaker to open, with a response time of less than one-hundredth of a second.

In the event that the circuit breaker trips, the current rating will be visibly reduced, owing to the integrated overload and short circuit indicator. This indicator is designed to alert the user that an abnormality has been detected and that the circuit breaker needs to be reset. The indicator is visible on the exterior of the unit, making it easy to identify whether the circuit breaker has tripped or not.

In summary, the LELB1-1REC4-39500-25-V circuit breaker is an efficient, reliable and robust device for providing safe and secure operation of electrical systems. Its thermal-magnetic tripping system is designed to respond quickly and accurately to overcurrents, short circuits and arc faults, providing the user with peace of mind that their system is being safeguarded against the elements.
