Diodes - Zener - Single

The CDLL3018 is a single-pole, normally open, Contacting Electronic Device (CED) circuit breaker switch. It offers reliable, compact, and maintenance-free protection for overcurrents up to 800A. It can be used in a wide variety of applications, including circuit breakers, switchgear, motor starters, lighting systems, and other industrial applications.

The main components of the CDLL3018 are a pair of zener diodes, a resistor, and a contactor. The zener diodes are the core elements responsible for the working principle of the circuit breaker. The zener diode is a type of semiconductor device that is capable of breaking an electric circuit when a certain threshold of current is exceeded. The zener diode works by opposing an increase in voltage by increasing the current passing through it. When the current exceeds a certain point, the diode will break the circuit, preventing further damage.

In the CDLL3018 circuit breaker, the two zener diodes are connected in series with the resistor. The resistor works to limit the maximum current passing through the circuit. When an overcurrent occurs, the voltage drop across the two diodes deter the rise in current. The current across the two diodes is limited and the current is discharged over the resistor. At the same time, the contactor is activated, breaking the circuit and preventing further damage.

The CDLL3018 is a versatile and reliable circuit breaker switch that offers a wide range of application possibilities. It can be used in residential, commercial, and industrial applications. It is ideal for use in a variety of electrical applications, including circuit breakers, switchgear, motor starters, lighting systems, and other industrial applications. It is also suitable for protection against overvoltage and undervoltage, as well as protection against overcurrents up to 800A.

In summary, the CDLL3018 is a circuit breaker switch that offers reliable and compact protection for overcurrents up to 800A. It is composed of two zener diodes, a resistor, and a contactor, making it an ideal choice for a variety of electrical applications. The key working principle of the circuit breaker is based on the zener diodes, which provide a voltage drop to limit the current in the circuit. This ensures that the current does not exceed a certain level and provides reliable protection against overcurrents.
