Delixi CDW6i-4000AF frame air circuit breaker ACB

Delixi CDW6i-4000AF frame-type air-circuit breaker (ACB) is a high-performance electrical device, which is mainly used in power distribution networks to distribute electrical energy and protect power lines and equipment. The following is a detailed introduction:

Technical parameters:

Rated current: It can reach 4000A.

Rated voltage: The rated voltage range is wide, generally covering 415V - 1140V and other levels.

Frequency: Applicable to 50Hz/60Hz AC circuits.

Number of poles: There are two options of 3 - pole and 4 - pole.

Breaking capacity: Ics can reach up to 135kA, and Icu can also reach up to 135kA, with strong breaking ability.

Product features:

High - speed chip: It adopts DSP 32 - bit high - speed processing chip, with fast data processing speed, which can quickly respond to fault signals and realize protection functions in time.

Excellent arc - extinguishing performance: The innovative multi - layer metal mesh design of the arc - extinguishing chamber can achieve real non - arcing, which is safe to use and has little impact on surrounding equipment.

Compact volume: The volume of 4000AF is about 20% smaller than that of similar products, which can reduce the size of the power distribution cabinet and save costs.

Protection functions: It is equipped with an intelligent controller, which can provide overload, undervoltage, short - circuit, single - phase grounding and other protection functions. At the same time, it may also have an alarm without tripping function, which can accurately protect lines and equipment and ensure the continuity and stability of power supply.

Installation and applicable environment:

Installation method: There are two installation methods, fixed - type and draw - out type, which are convenient for installation in different scenarios. The wiring methods are horizontal rear - connection and vertical rear - connection, which are convenient for connection with the circuit system.

Applicable environment: The ambient air temperature is normally - 5℃ - + 40℃, and the average value within 24h does not exceed + 35℃. It can also be used in the extreme temperature range of - 40℃ - + 70℃. It is applicable to the environment with an altitude of 5000m and below.

Intelligent and accessory configuration:

Intelligent function: It can fully realize the "four - remote" functions of remote control, remote adjustment, remote measurement and remote signaling, and can be intelligently monitored across the network through the network. It is convenient for remote operation and management, and can be connected with the intelligent power grid system.

Accessory configuration: It can be equipped with a variety of accessories. For example, locking and interlocking accessories such as button protection locks and mechanical interlocks can ensure operation safety; remote - operation accessories such as shunt trip coils and undervoltage coils can realize remote control; it can also be equipped with auxiliary switches of different specifications according to requirements, such as OF3266 auxiliary switch (6 - open 6 - closed).
