We are all deeply invested in ensuring sound safety mechanisms for our homes and offices. All reckless fire hazards can cause long-term damage to our lives and properties. However, you can easily avoid such damage with good-quality circuit breakers.

MCB and MCCB serve as electrical fuses. They are the two types of circuit breakers that bind the integrity of electrical circuits by protecting them from short circuits and current overload.

In the next section, we have discussed the significant difference between MCB and MCCB that you should know.

What are MCBs and MCCBs?

MCB is an electrical device that ensures complete protection against current overload. MCBs are circuit breakers that act like fuses on the passage of an excessive current. In such cases, MCBs operate like a switch and create an open circuit to prevent fire hazards.

MCCBs, on the other hand, are circuit breakers which are useful in controlling excessive current flow that may otherwise lead to short circuits or overload.

The outer covering of MCCBs has a protective and sturdy case. In case of a ground fault, MCCBs tactfully channel the excessive current flows directly to the ground.

Some differences between MCCBs and MCBs:

There are some striking differences between MCB and MCCB. They are listed below:

●      Full form:

Though both are circuit breakers, MCBs and MCCBs are different in terms of functionality. MCB means miniature circuit breaker, while MCCB means moulded case circuit breaker.

●      Purpose of use:

MCBs protect an electrical circuit from overloading, while MCCBs protect the circuits from short-circuit currents.

●      Dimensions:

The dimensions of MCBs are much smaller than the dimensions of MCCBs.

●      Tripping circuit:

The tripping circuits differ in the case of MCBs and MCCBs. In the case of MCB, the tripping circuit has a fixed value. For MCCBs, you can have movable tripping circuits.

●      Rated current:

The rated current of MCB is only 125A, while MCCBs can have a current rating of 1600A.

●      Current flow:

For circuits with a low current flow rate, you can use MCBs. Use MCCBs for electrical circuits with a higher range of current flow.

●      Cost:

MCBs are much more pocket-friendly than MCCBs.

●      Mode of operation:

Unlike MCBs, you can operate MCCBs remotely using shunt wires.

●      Areas of application:

MCBs are most useful in residential buildings where the circuits have low current flow. On the other hand, MCCBs easily handle high currents in industrial and commercial buildings. MCCBs mostly find their applications in heavy-duty machinery like welding machines, electric motors, generators and electric feeders.
