An Air Circuit Breaker (ACB) is a main part of low-voltage power distribution with a simple but very important job: to protect electrical systems by interrupting overloads, short circuits, and ground faults at the distribution panel level. Consider the tight uptime requirements and strict safety and environmental dictums of California Industry, and you will connect the dots that lead to a non-negotiable need for dependable, serviceable protection that keeps production running and compliance intact.
The typical use case is any application where high current interruption capability and selective protection are required. This includes main incoming panels, large distribution buses, and feeder protection to critical loads. This safety component is not the same as smaller circuits, as they are designed for branch circuiting and an ACB is built for heavy switching. It is different from a Vacuum Circuit Breaker, as it usually comes in for low-voltage applications as opposed to medium.
The breakers have easy maintenance (often draw-out style) and can usually integrate with advanced trip units that provide measurement, diagnostics, and communications. Susol/Metasol series by LS Electric is all of that and more. The product lineup covers a range of low-voltage distribution needs; and they are both KEPIC (Nuclear rating) and LR, ABS, DNV, KR, BV, GL, RINA, NK certified. All that, and backed by modern trip-relay features and modular designs suitable for industrial and commercial installations.

A global leader that is surprisingly overlooked in America, despite their high efficiency, low-cost products. You can take a look at our [Full range of products] here or continue reading to see why the ACBs provided by LS are the best choice for your application)
A direct reduction of risk and running costs with a visible mixture of reliability, maintainability, and operational clarity with air circuit breakers. ACBs can handle high fault currents without creating problems due to high wear and tear. Many thanks to draw-out designs, breakers can be isolated and services without the need to shut down the entire panel. The downtime reduction is tremendous with this method. LS Electric’s ACBs offer all these benefits (general to all ACBs) and adds onto it by providing frame and trip configurations that support longevity and stable performance under repeated switching.
Then there is the advanced protection and control features. Modern ACBs come with configurable digital trip units for overcurrent, short-circuit, ground-fault, and protection coordination. With these units you are also enabled to meter voltage, current, and power, log events, and integrate via Modbus/RS-485/ethernet; this way your controls and SCADA can see what the power side is doing, all in real time.
Moving on to safety and compliance, ACBs bring arc fault exposure to a minimum and facilitate safe service access. All of California’s mandatory workplace safety measures are met. The robust mechanical and electrical designs, especially in ACBs sourced from LS Electric, make selective coordination easier. Chance of a nuisance trip is very low and protection granularity for critical loads are increased.
Finally, there is the matter of lifecycle economics. ACBs are a safe, high ROI investment because they can be serviced in place, exchanged via their easy-to-use cradle, and integrate with diagnostic systems. Older circuit breaker models cannot say the same. For facilities that need predictable O&M budgets, that’s a huge advantage.
As per LS Electric ACB catalogs and technical manuals, the ACB families (Namely Susol, Metasol, AV/AW series and their variants) are modular, protection intelligent, and application flexible components with numerous benefits. Here are 7 facts listed for you to be better familiar with these benefits:
With the diversity of use cases and space limitations, and load weights across the industry, LS Electric offers multiple ampere frames, this way covering common industrial needs. ACB [Catalouges] provide call out frame sizes and configurations that support up to several thousand amps. For this reason LS Electric air circuit breakers are suitable for main distribution and heavy feeders.
Even the most robust short-circuit interruptions and the heaviest making duties are no match for LS Electric’s ACBs. The components are like city superheroes, protecting downstream equipment and reducing thermal/mechanical stress during faults. Models come in a verity, covering industrial applications up to utility-grade setups.
Integrated advanced digital relays are at your service to provide protective functions, measurement, diagnostics, and communication. Fault data will be delivered to you instantaneously, as well as energy metrics and a path to remote status integration. These will come in handy in facilities that track data like uptime and energy use.
You can go for fixed options, but you can also go for draw-out models if you want easy access to breakers for testing and replacement. This way, there will be no need for the entire operation to stop for a simple replacement. Also, this way you will have a reduced risk of full panel outages.
The thing about LS Electric is that they prioritize modularity and produce products that can be used by anyone who has the need for the component. LS is manufacturing a range or models and numerous accessories to go with them; any product can be customized to match your specific needs.
Speaking of models, LS ACB lineup includes ones rated for harsh environments or renewable energy applications. Some series are even designed especially for higher altitudes and challenging sites. California industry projects are familiar to be on rooftops or coastal installation, and this makes LS ACBs ideal.
AS you can see in the product literature, all components are in compliance with IEC and UL options. Test/operation cycles and electrical/mechanical endurance have been document for engineering spec compliance checks.

But despite that, it would be a good idea to specify some parameters so as to facilitate your selection. As you are aware, you need to strike a balance between current ratings, fault interrupting capacity, protection functions, and physical diameters.
To start, assess your facility’s maximum load and prospective fault currents. LS Electric offers various frame sizes and trip unit configurations. You are sure to find a breaker that handles peak demands without taking up much space.
Next, consider your need for digital trip units with metering and communications. This is especially important if your facility requires deeper visibility into the operation. Some models even include use-friendly interfaces alongside remote monitoring options.
Installation environments also matter a lot. You need to determine if your unit will be exposed to harsh conditions like dust, moisture, or vibration. LS Electric always makes models with consideration that someone with a facility in such conditions might need consistent use.
Once you have all this data, you can choose your ACB. This is where you should contact experts. We provide consultation to engineers, OEMs, and integrators from various industries. We are ready to help businesses in California and all of West Coast to evaluate these variables.
