What Is an Air Breaker and How Do They Work?

Just as molded case circuit breakers, MCCB, air circuit breakers, ACB, is device that is in place to provide protection from an electrical surge or short-circuit.  The main difference is the amps they protect; ACB can withstand higher short circuit currents and mechanical stress because of the arc extinguisher element then MCCB can.  There are a variety of air circuit breakers and switching gears available to purchase.  Air circuit breakers have replaced oil circuit breakers because of their resiliency, performance, ease of installation, and low maintenance level. 

Three Types of Air Break Circuit Breaker

The three main types of air break circuit breakers include: plain break, magnetic blowout, and air chute.  Their main application is for use in maintaining indoor voltage and switch gears.

Plain Break

The simplest of all air circuit breakers is the plain brake.  Two horns shape the main point of contact.  This creates an arc that extends from the tip of one to the other. 

Magnetic Blowout

In higher voltage capacity’s, up to 11KV, magnetic blowout air circuit breakers are used.  The arc extension gets by the magnetic field that is made from the current in blowout coils.

Air Chute

Air chute air break circuit breakers have main contacts of copper and conduit which are in the closed position.  They are most often silver plated and have a low contact resistance.  The arching contacts are created from copper alloy and are resistant to heat and are solid. 

Air circuit breakers are most often used for controlling the power station auxiliaries and industrial plants.  They provide protection to electrical machinery such as transformers, capacitors, and generators.  Where ever there is a possibility of fire or explosion, air circuit breakers are most often installed.   They offer a higher resistance to power that allows an increase in the resistance of the arc by splitting, cooling, and lengthening.  The main drawback in air circuit breakers is that the arc chute principle is less efficient under low currents where electromagnetic fields are weak.

CES 2019: Currant Introduces First AI-Powered Smart Wall Outlets

CES 2019: Currant Introduces First AI-Powered Smart Wall Outlets

AI moves into your wall power outlet.

Currant the Currant Smart Wall Outlet ahead of CES 2019. It will be the first AI-powered in-wall smart outlet that analyzes power usage and creates personalized, easy-to-implement suggestions for consumers, contractors, business owners, and real estate managers to automatically power off devices and appliances, cutting excess electricity usage and helping to save money on electric bills. Currant’s Smart Wall Outlet will be available in a 15 amp version for homes and a 20 amp outlet designed for the commercial market. Both the home and commercial models can be controlled by the Currant App, Amazon Alexa, or Google Home.

The new Smart Wall Outlet is designed to replace traditional outlets with duplex tamper-resistant receptacles that can be easily installed in commercial businesses and new construction as well as consumers’ existing homes. Each in-wall unit analyzes real-time electricity usage, displaying it in intuitive graphs that break down energy consumption and cost by hour, day, month, or year. Customers can use the Currant App to monitor anything plugged into the outlet, effectively controlling power running through the outlet to ensure that they’re fully in control of all their devices and appliances, whether they’re down the street or across the country. And, like all Currant outlets, Smart Wall Outlet models are calibrated using high-precision test equipment.

In addition to Smart Wall Outlets, Currant also announced that it has added a number of new features to its WiFi Smart Outlets. Available January 8, these features include the ability to lock the outlet so it cannot be turned on or off except through the app, which is particularly useful for parents looking to prevent kids from using certain appliances for safety reasons, such as an iron, or who want to set limits on gaming consoles.

Outlet locking is also valued by people who want to prevent things like a WiFi network from cutting out in the event someone accidentally turns it off, or business owners who want to shut off power to specific outlets or devices and not enable them to be turned back on from the outlet itself. In addition to the ability to lock the outlets, Currant will offer customized alerts that notify people when their rules take effect and when devices are using certain levels of power.

“We are on a mission to help reduce the insanely high levels of energy consumption in the United States,” said Hasty Granbery, founder and CEO of Currant. “To that end, we are thrilled to announce our newest offering in what will be a long line of energy-saving smart home and commercial products. Currant Smart Outlets will work in essentially every environment — home or commercial space. We can help anyone cut energy consumption, save money, and make a positive impact on our world without any inconvenience to their day-to-day lives or activities.”

Currant Outlets run on both WiFi and Bluetooth, assisting with ease of setup and control. The Currant Smart Wall Outlets will work seamlessly with existing Currant Smart Outlets, creating a Bluetooth Mesh Network throughout the building that can be used to control any outlet within range, enabling control in areas where a WiFi network is weak or unavailable. In addition, when several Currant Outlets are used together, the outlets can prioritize which communication protocol to use so only a subset of outlets are using WiFi.

Customers can get started with an in-wall outlet within minutes and easily connect to the Currant App, which is available for iPhone and Android. The app automatically detects the outlet and displays real-time information on energy usage. Customers can opt to set outlet-specific rules right away in order to turn the power on and off according to their preferences and schedules or they can use it as a normal outlet before receiving tailored suggestions for usage based on what is plugged into the outlet, the amount of energy consumed, and any unique usage patterns for the space.
