What does kA mean on fuses?
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.
What does kA mean on a breaker?
kA rating on a circuit breaker is the maximum short-circuit current value that a circuit breaker can break at a given voltage and phase angle (cos ϕ). It can also be defined as I cu. If the current flows through the breaker exceeds this value, the circuit breaker could be damaged and be useless.
What does 10kA mean on breaker?
The 10 kA you see on a circuit breaker is the interrupting rating of the circuit breaker, that is, the largest current that it can safely open. It is usually written as 10 kA rms symmetrical. The rms indicates that it is rated to interrupt 10 kA root mean square current.
What is the meaning of kA in electrical system?
A kiloampere (kA), is a decimal multiple of the ampere, the SI unit of electric current. To: ampere. kiloampere.

What is the meaning of 6kA?
A value of 6kA means that the circuit breaker can withstand 6,000 amps of current under fault conditions during the brief time it takes to trip the Circuit Breaker.

How do you calculate the Ka rating of a transformer?
Transformer short circuit fault current Calculations Short circuit fault current I(fault) in kilo amps is equal to 100 times of transformer’s rating S(kVA) in kVA divided by the multiplication of root 3, transformer’s secondary voltage V(V) in Volts and percentage impedance in percentage.
