What Is an ACB?
An ACB, or air circuit breaker, is a low-voltage circuit breaker that uses air as the arc extinguishing medium when the contacts open under load or fault conditions. It is commonly used in higher-current power distribution systems where main incoming protection, bus coupler switching, selective coordination, and service accessibility are more important than compact breaker size.
Air as the Breaking Medium
The breaker interrupts current and extinguishes the switching arc in air, which makes ACB products suitable for low-voltage systems with higher current demand.
Main Distribution Protection
ACB products are often used as main incoming breakers, bus coupler breakers, or high-current feeder breakers inside switchboards and distribution assemblies.
High-Current Low-Voltage Use
Compared with smaller breaker platforms, ACB products are better suited to applications that need higher current coverage, service access, and more advanced protection control.

⎯⎯ Selection Focus
Why This ACB Layout Works
The page follows the main factors normally used when reviewing ACB products for quotation, comparison, and switchboard matching.
Frame and Current Logic First
The page starts with 2000A, 4000A, and 6300A frame logic because current coverage is usually the first step in ACB selection.
Installation Type is Separated Clearly
Fixed and draw-out types are presented as distinct choices so maintenance strategy and switchboard design are easier to compare.
Trip Unit and Accessories are Included
Many ACB decisions depend on controller level and accessory logic, so those points are kept in the main comparison flow instead of being hidden.
RFQ Path is Kept Simple
The page closes with the exact project details that are most useful for ACB quotation, helping the buyer move from product review to inquiry faster.

Frequently Asked Questions About Cable Tie Products
What is an ACB used for?
An ACB air circuit breaker is used in low-voltage distribution systems as a main incoming breaker, bus coupler breaker, or higher-current feeder breaker. It is commonly selected for switchboards, generator systems, industrial plants, and large commercial power assemblies.
What current range does the VIOX ACB product scope cover?
The VIOX ACB product scope covers current ratings from 630A to 6300A across 2000A, 4000A, and 6300A frame sizes, which helps organize the range for different low-voltage distribution capacities.
How do I choose between fixed type and draw-out type ACB?
Fixed type ACB is commonly used for stable panel integration, while draw-out type ACB is generally preferred when service access, isolation during maintenance, and easier breaker replacement are important in the switchgear workflow.
What trip unit options are common on ACB products?
ACB products commonly include different intelligent controller levels such as M, H, 3M, and 3H options. The right choice depends on the required protection functions, operating display, monitoring depth, and communication needs.
