Circuit breakers are essential components in an electrical system, responsible for interrupting the flow of electricity when a fault or overload is detected. From residential homes to commercial buildings, the purpose of circuit breakers is to protect against the damages of over-currents, which can lead to fire and other damages.LELK1-1-52-65.0-AV-01-V circuit breaker is a modern three-pole, adjustable, type AC circuit breaker with current and voltage ratings of 65A and 550V. It is mostly used in residential and small commercial applications as a main protection device. It has various features that set it apart from other circuit breakers, such as adjustable current settings, multiple voltage ratings, adjustable trip times, and adjustable thermal-magnetic trip settings.The primary application of this circuit breaker is to protect against short-circuits and overloads on AC electrical systems. When the current reaches a certain level, the breaker will "trip" or open the circuit, stopping the flow of current and preventing further damage. It also offers manual reset capabilities, meaning it will shut down and stop the flow of electricity when the button is pressed, and once the issue has been addressed, it can be manually reset to restore power.The working principle for this circuit breaker is based on the combination of thermal and magnetic principles. When a fault or overload is detected, the thermal and magnetic components of the circuit breaker work together to shut off the power before any significant damage can occur. The thermal component of the circuit breaker works by measuring the ambient temperature of the system. When the temperature of the system increases, a heat-sensitive element within the breaker increases its resistance. This increase in resistance not only increases the amount of current flowing through the breaker, but also increases the total power consumed by the breaker. The magnetic component of the circuit breaker works by measuring the electromagnetic forces generated by the current flowing through the system. When the level of these forces exceeds a certain level, a magnetic field is generated, which causes a latch to open inside the breaker, thereby opening the circuit and interrupting the flow of electricity.In conclusion, LELK1-1-52-65.0-AV-01-V circuit breaker is a reliable and efficient three-pole, adjustable, type AC circuit breaker designed to protect against the damages of over-currents. It combines the effective working principles of thermal and magnetic operation to accurately identify and quickly interrupt the flow of electricity, saving sensitive electrical components and preventing the occurrence of fire and other damages.
