By connecting software to its electrification, robotics, automation and motion portfolio, ABB pushes the boundaries of technology to drive performance to new levels. On the other hand, when it comes to industrial use or any other heavy-duty requirements, MCCB is the best suited.ABB (ABBN: SIX Swiss Ex) is a leading global technology company that energizes the transformation of society and industry to achieve a more productive, sustainable future. Obviously, when it comes to home use or some light work, the MCB is better preferred due to low energy requirements. MCCB is said to be more suited for higher energy due to the possession of better capacity than MCB, whereas MCB is usually provided for low energy requirements, hence they are best suited for them. For the sake of convenience, MCCB is equipped with a special feature of being tripped only by remote as their units have electrical motor operators. Whereas MCCBs being rated from 10 to 2500 amps comes with an adjustable trip feature so they can cater for high current circuitsĪlthough an MCCB possesses a higher capacity than an MCB, both are classified under low voltage circuit breakers and should respond to standards set by the IEC 947. MCB being rated under 100 amps doesn't come with the feature of the adjustable trip, hence they always cater low current circuit.
Hence this states that MCB is usually used for low energy requirements such as home wiring or small electric circuits, on the other hand, MCCB is more suited for high energy requirements. MCCBs provide amps between 2500-10 and their interrupting rating ranges from 10,000 amps to 200,00 amps. Whereas MCCB has the characteristics of the adjustable trip which is used in higher models. MCB’s trip characteristics may not be adjusted since they are mostly provided to low circuits with the MCB rated 100 amps with an interrupting rating of under 18000 amps.
MCCB’s are subjected to high current, therefore they need proper maintenance and can be maintained by regular cleaning, lubricating, and testing. These work on principles of electromagnetism and cam also be disconnected manually. These are usually used in PV systems in place of miniature circuit breakers. MCCB provides overload protection via the temperature-sensitive component. They are being used for a wide range of frequencies with the current rating up to 2500A and adjustable trip settings. It is used to protect the electric circuit from the flowing of excessive current which can further cause damages such as overload and short circuit. MCCB is the short form for a moulded case circuit breaker. The time duration if exceeds a certain value the MCB trips and breaks the circuit thus rendering the overload dysfunctional in damaging the appliances and further circuit. This means that they function whenever there is an overload or higher flow of current for a longer duration of time, the duration which can hamper the normal functioning of the circuit. MCBs work on a time-delay tripping mechanism. Image will be uploaded soon MCB Electrical MCB is a kind of a better version of a fuse.

The mechanism of MCB has 3 possible positions, ‘ON’, ‘OFF’, and ‘TRIPPED’, hence the breaker provides manual means of opening and closing of the circuit. In conditions such as short circuit or overload, these devices trip by themselves hence saving the house by the damages caused by a short circuit or overload or as the case may be. Its primary function is to break the circuit when the current flowing through the circuit reaches past a certain set limit. MCB is the acronym used for the miniature circuit breaker and is commonly used in our day to day lives.
