5 Things to Know about MCCB Switchgears

Working with electricity and heavy-duty electric circuits requires necessary precautions. Proper electrical safety gear, like Molded Case Circuit  Breakers (MCCB), are extremely useful as they prevent electrical accidents and protect electrical appliances from sudden electrical surges. 

Listed below are five things you must know about MCCB Switchgears:

  • MCCBs act as more sophisticated versions of the usual Miniature Circuit Breakers (MCB) are available in the market. They help in protecting electrical appliances from sudden electrical surges, circuit overloads, and short circuits.
    • An MCCB protects the entire electronic circuit from circuit overheating as well. An MCCB operates as an electromagnetic device that offers protection from electrical accidents and circuit meltdowns.
  • MCCBs are used to prevent the overloading of electrical circuits. They are built to detect excessive electrical loads on a circuit using a temperature-sensitive mechanism.
    • MCCBs contain a bimetallic magnetic component that heats up when there is excess electricity and breaks the circuit, thus stopping the flow of electricity. Once the usual operating conditions resume, the bimetallic component cools down and the MCCB allows the usual flow of electricity through the circuit once again.
    • The average MCCB takes about 0.04 seconds to break a circuit due to the presence of a bimetallic strip. This bimetallic strip heats up faster when there is a surge in electricity and trips to break the circuit. Modern MCCBs are also equipped with a manual disconnection switch which can be remotely operated using a shunt wire. 

Depending on their security phases or poles, MCCBs are available in 2,3, and 4 pole variants. These poles are hot wire markers across the neutral line, which disconnects the circuit during electrical surges by tripping. If you want the best deals on MCCB 100-amp 4 pole price, try Schneider Electric.

Depending on their operating current rate and response time, MCCB gearshifts are available in five different types - Type B, Type C, Type D, Type K, and Type Z. 

 Here’s how each of these types works:

  1. Type B works effectively against lower current surges, with a response time of 0.04 seconds. 
  2. Type C also has a response time of 0.04 seconds for moderate surge amounts. 
  3. Type D is an industrial-grade MCCB that can break the circuit within 0.04 seconds for heavier loads like large vending motors, and higher electrical surges.
  4. Type K and Z are used by industrial sectors that deal with extremely high voltage limits, heavy loads, and high electrical surges.

The types D, K, and Z are used across electrical distribution centers and for heavy equipment.

Final Words

The MCCBs are very popularly used across the globe in industrial and domestic spheres to protect electrical appliances from damage from unprecedented electrical bursts. They are essential protective devices and hence should only be curated from authentic, trustworthy sources. 

Hence, if you are looking for good quality MCCBs, Schneider Electric is one of the most trusted brands that is a one-stop place for all your electrical needs, including MCCB Switchgears. You can avail fascinating deals on MCCB 100-amp price from Schneider Electric alongside several other offers.
