5 Benefits of using Circuit Breaker in Commercial Industries

A circuit breaker is a switch that automatically blocks the current of an overloaded electrical circuit, ground faults, or short circuits. It is an electrical safety device. After protective relays identify a defect, circuit breakers “trip,” cutting off current flow. Circuit breakers, in contrast to the fuses that were previously used, are typically not destroyed, allowing for reset as opposed to replacement. Both home and industrial uses require circuit breakers in the USA.

Important Features of Circuit Breakers

Circuit breakers in the USA are made using three main purposes: 

  • Monitoring 
  • Switching 
  • Protection

When current reaches an unsafe level due to overload, short circuit, or other electrical defects, circuit breakers are designed to “break” (discontinue) the flow of power to safeguard people and equipment. For residential usage, different types of circuit breakers may have design characteristics that give ground fault and/or arc fault protection. 

For commercial and industrial use, different types of circuit breakers in the USA have design features that provide metering, alarm, and remote on/off control. 

Circuit Breakers for Industries

Industrial circuit breakers are built to handle currents that are far more powerful than those found in a conventional home or residence. The industrial circuit breakers will be included into the electrical systems of factories, warehouses, and other major businesses. Industrial circuit breakers are often categorized based on their structural characteristics, their construction, how interruption occurs, and their volt class.

Frequently Used Circuit breakers in Industries

Following are some of the best circuit breakers in the USA that are used for commercial use in industries:

Industrial Circuit Breakers at High Voltage:

Industrial high-voltage circuit breakers are typically made at voltages of 72.5 kV or higher. Power transmission networks and circuits will contain these high voltage circuit breakers. Typically, they are the solenoid-operated circuit breakers with current-sensing protection relays that use current transformers for power.

Benefits:

  • These high voltage circuit breakers in the USA at substations are crucial for shielding the connected buses and equipment from a variety of electrical problems, such as overloads and earth or ground faults.
  • By the way they put out an arc, high voltage circuit breakers are generally categorized. Air blast, bulk oil, minimal oil, a vacuum, and the SF6 (Sulphur hexafluoride) gas are some of the techniques used to put out the arc. 
  • Due to environmental concerns and the expense of oil spills that can occur with oil-type circuit breakers, the majority of more recent industrial circuit breakers now use SF6 gas to extinguish the arc.

Industrial Circuit Breakers for Medium Voltage:

Similar to high-voltage industrial circuit breakers, medium-voltage circuit breakers are categorized based on how they put out an arc, such as with an SF6 circuit breaker, an air circuit breaker, or a vacuum circuit switch breaker.

Benefits:

  • Circuit breakers for medium voltages can handle voltages of 1 to 72 kV. 
  • Many of these switches can be mounted either individually outdoors or in switchgear-like lineups inside metal enclosures for indoor use. 

Industrial Circuit Breakers at Low Voltage:

Low voltage circuit breakers in the USA include miniature circuit breakers with current ratings under 100 and molded case circuit breakers with ratings no higher than 2,500A.

Benefits:

  • Low volt circuit breakers are frequently made for voltages rated at less than 1 kV. 
  • These are widely used in both industrial facilities and household and commercial settings.

Electric circuit breakers for industry:

A magnetic circuit breaker uses an electromagnetic solenoid with a current-dependent magnetic power design. The solenoid’s pull grows strong enough to release a latch that seals the contacts as the current flowing through the breaker rises over the preset threshold, which is effectively the breaker’s rating, and that circuit is severed.

Circuit breakers with a thermal and magnetic field for industry:

Thermal electromagnetic circuit breakers use both bimetallic strip trip and electromagnetic circuit-breaking techniques. While the bimetallic strip reacts to less severe but persistent over-current circumstances, the electromagnet reacts promptly to massive current surges or short circuits. 

Benefits:

The thermal component of the thermal magnetic industrial circuit breakers provides an inverse time response, allowing lesser overloads to endure for a while but tripping considerably more quickly for the bigger over-currents. 

SF6 High Voltage Industrial Circuit Breakers:

The gas Sulphur hexafluoride surrounds the contacts in SF6 industrial circuit breakers, quenching the arc that results.

Benefits:

  • In transmission level levels where heavy currents are present, industrial SF6 high voltage circuit breakers are typically used. 
  • For increased effectiveness, they can be added to gas-insulated small switchgears. 
  • To combat the liquefaction of SF6 gas at low temperatures, additional heating of these circuit breakers or a calculated de-rating of their capabilities may be required in cold areas.

FAQs

Are circuit breakers present in commercial structures?

Commercial buildings must have circuit breakers with uncompensated thermal tripping mechanisms and trip current levels that are adjusted based on the temperature of the surrounding environment.

What is meant by a commercial circuit breaker?

A circuit breaker is a switching mechanism used to stop unusual electric current flow. It is frequently used in homes and businesses to ensure electrical safety.
