Aptomat khí là gì?
An air circuit breaker, or ACB, is a low-voltage circuit breaker that interrupts current and extinguishes the switching arc in air. It is commonly applied where main incoming, bus-coupler or high-current feeder duties require greater current coverage, service access and protection control.
ACB selection is a switchboard engineering decision. Frame size, rated current, system voltage, poles, fixed or draw-out construction, interruption requirements, protection functions and accessories must be coordinated with the complete assembly.
W1-2000 ACB Series Overview
Compare the three published frame sizes before confirming installation type, poles, trip unit and accessories.
W1-2000 Frame Range
The published range is organized by frame size and current band. Final availability, interruption duty and accessories must be confirmed for the selected configuration.

How to choose an ACB
Start with the switchboard duty and available fault level, then select frame, current, construction and control configuration.
Frame and rated current
Match the continuous load, design margin and frame range without treating the frame rating as the operating setting.
System voltage and interruption duty
Confirm 415V or 690V system conditions and the required fault-interruption and withstand performance from the exact datasheet.
Cấu trúc cố định hoặc kiểu kéo
Choose fixed integration or withdrawable service access according to the switchgear maintenance strategy.
Trip unit and accessories
Define M, H, 3M or 3H controller needs, motor charging, shunt release, undervoltage release and auxiliary contacts.
Specify the complete switchboard duty
An ACB cannot be selected from rated current alone. Protection coordination, service method and control logic determine the final configuration.
Compare published ACB series
Published W1-2000 frame coverage from the original VIOX ACB page. Confirm the exact interruption ratings, controller functions and accessories against the selected configuration before specification.

ACB Selection Questions
Câu trả lời nhanh để so sánh sơ bộ các dòng sản phẩm trước khi xác minh chi tiết mạch điện.
ACB được sử dụng để làm gì?
An ACB is commonly used as a main incoming breaker, bus coupler or high-current feeder breaker in low-voltage switchboards, generator systems, industrial plants and large commercial distribution assemblies.
What current range does the VIOX W1-2000 scope cover?
The published VIOX W1-2000 scope covers 630A to 6300A across 2000A, 4000A and 6300A frame sizes.
How do fixed and draw-out ACBs differ?
A fixed ACB is integrated directly into the panel, while a draw-out ACB supports withdrawal for isolation, maintenance and replacement according to the switchgear design.
Which trip-unit options are listed for the W1-2000 series?
The original VIOX page lists M, H, 3M and 3H intelligent controller options. Exact protection, monitoring and communication functions must be confirmed for the selected controller.
What should be included in an ACB quotation request?
Provide system voltage, rated current, frame size, poles, fixed or draw-out preference, fault-level requirements, trip-unit functions, accessories, application, quantity and target market.
