The main difference between the two is their capacity, with the MCB rated under 100 amps with an interrupting rating
What is a 6kA circuit breaker?
Single pole mini circuit breaker with 3A current rating, offer optimum and efficient protection for branch and control circuits. The 6kA breaking capacity of this mcb makes it ideal for commercial and industrial applications.
What is 10kA in MCB?
MCB Breaking Capacity : Breaking capacity can be defined as the maximum level of fault current which can be safely cleared. It is written as in numerals like in in example it is 10000. It means it 10000A = 10kA. ... It means that it does not allow fault to get it's peak and trip before that.
How many amps is a 10kA breaker?

Which ampere MCB is best for home?
The best-suited type of MCB for domestic appliances, where the current load is medium, is type C . Type C MCB trips off when the flow of current is 5-10 times more than normal. Type D MCB has a high resistance as they can withstand up to 10-20 times the current rate.
What is rated current in MCB?
(2) Rated Current (In /Ie):
It is the current value above which overload protection is tripped . For MCB it is fixed while in MCCB the rated current is an adjustable range instead of a fixed value. Standard rating of MCB is 1A, 2A, 3A, 4A, 6A, 10A, 13A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 100A for MCB.
What is MCB full form?
MCB stands for Miniature Circuit Breaker . It automatically switches OFF electrical circuit during any abnormal condition in the electrical network such as overload & short circuitconditions.
What does kA mean on Breakers?
kA rating of an MCB or an MCCB is the maximum current it can safely interrupt in case of a short circuit. If the current goes beyond this value, the circuit breaker could be damaged. kA rating is known as the short circuit withstand capacity or ultimate breaking capacity of a circuit breaker.
How do you size a breaker?
To calculate the breaker size, simply divide the adjusted wattage by 240 volts to find the rated amperage needed for your subpanel . Often, the result is not a common circuit breaker size. and you can simply round up to the next higher size of the breaker.
What is the use of MCB in electrical?
Miniature circuit breakers are used to safeguard homes from overload . Due to their capacity to handle large amounts of electricity, they are much reliable and safer than a fuse. One of the greatest advantages of an MCB is that it ensures equal distribution of electrical energy across all the devices.
How many outlets can be on a 15 amp breaker?
Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.
What does 120 240v breaker mean?
Jun 13, 2005. You will need to have a 30 amp/240 volt line installed. 120/240 refers to the common voltage into a typical home . There are two lines that are 120 volts each supplying power to two different legs in your breaker/fuse panel.
How many amps is 5ka?
| Kiloampere [kA] Ampere [A] | 0.1 kA 100 A | 1 kA 1000 A | 2 kA 2000 A | 3 kA 3000 A |

What is a Type 2 MCB?
For example, a Type 2 MCB has a multiple of 7 (from {Table 3.3}) so a 30 A device of this type will operate over the time range of 0.04 s to 8 s at a current of 7 x 30 A = 210 A.
What is Type B and C MCB?
Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device).
