The current rating of an MCB is 100 amperes, while an MCCB has a current rating of between 10 to 200 amperes. They have a major difference when it comes to their interrupt rating - the maximum current that a self-operating electrical switch can block without malfunctioning. Key Differences Between MCB and MCCB The MCB is a type of switch which protects the system from overloaded current whereas the MCCB protects the system from over temperature and short circuit current. The MCB stands for Miniature circuit breaker whereas the MCCB stands for moulded case circuit breaker.
What is the Difference Between MCB and MCCB? Practical Applications
Differences between MCB and MCCB are: 1. Abbreviation and definition MCB stands for m iniature c ircuit b reaker. MCCB stands for m olded c ase c ircuit b reaker. Both devices protect installations against overcurrent and short circuits. They have also an isolation function. MCBs are suitable for residential and light commercial applications due to their quick response and lower breaking capacity. MCCBs are equipped for higher electrical loads in industrial settings, offering greater breaking capacity and adjustable settings. Vacuum Circuit Breaker Characteristics With rated current up to 3000 A, These breakers interrupt the arc in a vacuum bottle. These can also be applied at up to 35,000 V. Vacuum circuit breakers tend to have longer life expectancies between overhaul than do air circuit breakers. RCD (Residual Current Device / RCCB (Residual Current Circuit Breaker) Most people tend to confuse the differences between MCCB and MCB. Even though they are both circuit breakers, there are major differences between the two that make each uniquely qualified for specific jobs. MCB MCB stands for Miniature Circuit Breakers.
What is MCCB? Functions, Components and Applications of MCCB.
The major difference between MCB and MCCB The principle of operation of MCBs is based on the thermal property of current whereas MCCB is a microprocessor-based device that uses current sensors to measure the magnitude of current and isolate a circuit. The maximum normal current rating of an MCB is 125A whereas that of an MCCB is 1600A. Current Rating: MCBs are designed to handle lower current ratings, typically up to 63 Amps, while MCCBs are designed to handle higher current ratings, typically up to 2,500 Amps or more. Size and Weight: MCBs are smaller and lighter than MCCBs, making them easier to install and handle. 1. MCCB Vs. MCB: Size An MCB, just as its name implies, is much smaller than an MCCB. This makes the MCB better suited for applications that require a smaller breaker. As you can see from the image above, the molded circuit breaker is the bulkier of the two. Another MCB vs. MCCB breaker difference is their maximum current rating. An MCB can handle a maximum current of 100A while an MCCB can handle currents of up to 200A. As such, you can use an MCCB for applications that require higher currents than an MCB can handle. These include heavy-duty industrial applications that involve large equipment.

Moulded Case Circuit Breaker Cost-wise, MCB is cheaper than MCCB. Obviously, due to the features discussed above, MCCB is costlier. These are the differences between MCB and MCCB. It must be up to the electrical engineer to decide what to choose if he knows the basic requirements and functions. MCCB vs. MCB: Understanding the difference. 16th Nov 2023 . Ever wondered how our electrical devices remain safe despite experiencing occasional faults or damages? Just as a busy street needs traffic signals to control traffic and maintain safety, electrical circuits also need something to protect the system from accidents..
MCB vs MCCB. Miniature circuit breakers (MCBs) are used to shut off smaller electrical circuits during an overcharge or short circuit. It has a lower capacity for breaking circuits up to 18000 amperage. A molded case circuit breaker (MCCB) is used in industrial applications for breaking larger circuits. It has an amperage range of up to 200000. Main Difference between MCB and MCCB MCB and MCCB Selection Difference between IEC 60898-1 and IEC 60947-2 IEC60898-1 IEC60947-2 Comparison Between IEC 69896-1 & IEC 60947-2 How to select MCB or MCCB at Different Circuit Levels? Difference between ICS & ICU in term of Circuit Breakers. Characteristic of MCB and FUSE
Difference Between MCB and MCCB MCB VS MCCB
Summary: 1.An MCB has less than 100 amps, while an MCCB goes as high as 2,500 amps. 2.The interrupting rating for an MCB is 18,000 amps, and up to 200,000 amps for an MCCB. 3.MCBs are mostly installed for home use, while an MCCB is generally utilized for commercial or industrial purposes. Differences Between MCB and MCCB: Full Name of MCB and MCCB: MCB: Miniature circuit breaker. MCCB: Molded case circuit breaker. Similarities Between MCB and MCCB: MCB and MCCB are electrical circuit breakers that provide an automatic trip time of fault and protect the equipment. MCB and MCCB are both low-voltage circuit breakers.
