Differbetween
The MCB stands for Miniature circuit breaker whereas the MCCB stands for moulded case circuit breaker. The tripping circuit of the MCB is fixed whereas in MCCB it is movable. ... When over current flows through the MCB and MCCB it shuts off the switch and hence protects the equipment from damage.

Which is better MCB or MCCB?
Though both are classified under low voltage circuit breakers as per the standards set by IEC 947, an MCCB has much more capacity than an MCB.
...
| Difference Between MCB and MCCB | ||
|---|---|---|
| Basis of Comparison | MCB | MCCB |
| Rating Current | 100 amps | 10 – 200 amps |
| Interrupting Rating | 1800 amps | 10k-200k amps |
Why we use Mccb instead of MCB?
Judging from their power capacities, MCB is mainly used for low Breaking capacity requirement mainly domestic. MCCB is mainly used for both low and high Breaking capacity requirements mainly industrial. Its trip characteristics are normally not adjustable since they basically cater to low circuits.
What is MCB and RCB?
The circuit breaker is the device of an Automatic circuit breaker or Miniature circuit breaker which trips the entire system and if any fault occurs, MCB is to protect the wires from the damage. Whereas, on the other hand, residual current device protects the life-threatening problems.
What is MCCB and its function?
A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or short circuit.
Which Rccb is best for home?
Different Ratings of RCCBs
For your household requirement, 32-63A rated RCCB which can withstand this current when tripping caused by the leakage of 30-100 mA is the normal range to select the best for your house. 30 mA is very sensitive and you may encounter few tripping without any apparent fault.

What is Rccb and MCB?
Miniature Circuit Breaker (MCB) is an electromechanical device which protects an electrical circuit and trip in case of overload and short circuit. While RCCB is a current sensing electro-mechanical device that breaks an electric circuit and trip in case of the earth fault.
Why is MCB used?
Miniature Circuit Breakers (MCBs) are electromechanical devices which are used to protect an electrical circuit from an overcurrent. The lead reasons for an overcurrent could be a short circuit or overload. Unlike a Fuse, MCB does not have to be replaced every time after a fault occurs and it can be reused.
Where is Rccb used?
A Residual Current Circuit Breaker (RCCB) is an important safety measure when it comes to protection of electrical circuits. It is a current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
What does an RCB do?
RCDs are protective devices used in electrical installations. They are designed to quickly break electrical circuits, and this prevents the user of the device from any serious harm as a result of an electrical shock.
What is an MCB breaker?
A Miniature Circuit Breaker is an electromechanical device designed to protect an electric circuit from over-current - A term to describe an electrical fault caused by either overload or short circuit.
What are the types of MCB?
Types of MCB based on Number of Poles
- Single Pole (SP) MCB. Single Pole MCB. A single-pole MCB provides switching and protection only for one single phase of a circuit.
- Double Pole (DP) MCB. Double Pole MCB. ...
- Triple Pole (TP) MCB. Triple Pole MCB.
