Circuit breakers are indispensable equipment in current electrical applications. The LEGBX66-37089-20-V circuit breaker is a miniature circuit breaker (MCB) designed for protecting electrical circuits from too high voltage and current overloads. It is suitable for residential protection, commercial power distribution and industrial protection applications.

The LEGBX66-37089-20-V circuit breaker has a compact design and features a high-interruption capacity, which makes it suitable for a wide range of applications. Its operating temperature range is from -25°C to +75°C, making it suitable for harsh environments. It has a high short-circuit breaking capacity (Icn) of 10 kA and a breaking capacity of 2.5 kA.

The LEGBX66-37089-20-V circuit breaker provides superior protection against overvoltage and overcurrent conditions. It is equipped with a sensitive trip unit that is capable of detecting small variations in current and voltage, allowing it to quickly and accurately identify overvoltage or overcurrent conditions and trip the circuit breaker in less than 4 milliseconds. The trip unit can also be adjusted to provide different levels of overvoltage and overcurrent protection.

The LEGBX66-37089-20-V circuit breaker features a fast-acting trip mechanism, which ensures it trip rapidly in the event of an overvoltage or overcurrent condition. The breaker can be reset manually or automatically, depending on the application. It is also equipped with a manual reset button that allows for easy resetting of the breaker.

The LEGBX66-37089-20-V circuit breaker is designed for use in a wide range of industrial, commercial and residential applications. It is suitable for use in industrial power distribution systems, commercial power distribution systems, residential light and power systems, telecom systems and other applications. It can be used as a main switch, switch disconnector, or surge arrester in these applications.

The working principle of the LEGBX66-37089-20-V circuit breaker is based on magnetic action. The current through the contacts of the breaker is converted into a magnetic field, either opening or closing according to the intensity of the field. When the current passing through the contacts exceeds the maximum limit, the strong magnetic field generated by the current will cause the contacts to open, effectively breaking the circuit and preventing further damage.

The LEGBX66-37089-20-V circuit breaker is a reliable and durable device that provides superior protection against overvoltage and overcurrent conditions. It is suitable for a wide range of applications, from industrial power distribution systems to residential light and power systems. The circuit breaker is able to quickly identify overvoltage or overcurrent conditions and trip the breaker in less than 4 milliseconds, protecting the circuitry from potential damage.
