Answer / arun

50 KA is its short ciruit current at which it will
breakdown.

Answer / gajajan kuhite

THE MEANING OF 50 KA IS THAT MAX. RATING OF BREAKER.MEANS IT
CAN WITHSTAND S.C. CURRENT UPTO 50 KA. WHEN S.C. CURRENT IS
GREATER THAN 50KA IT MEANS MCCB SHOULD NOT WITHSTAND & IT
MAY B DAMAGE.

Answer / rameshpaulaian

50kA - Short Circuit Current.

Answer / anil bhatia

50 KA is peak maximum curent or withstandind capacity of
MCCB upto which it will work or withstand, beyound this
limit it will damege .

Answer / sreenu

simply, it is a breaking capacity.

Answer / sagir

50kA means the fault current carrying capacity of said MCCB is up to 50000Amps. Above this rating the MCCB goes trip or damage. The protection capacity is 50,000Amps.

Answer / rajendran

Normally this 50 KA refers the Breaking capacity of the
circuit breaker



thanks

Answer / yadlapalli suresh

50KA means withstandable capacity of the breaker,,the current crosses 50KA ,the breaker get damaged even it is in trip condition ,,then we replace it with new breaker. ok

Answer / tt

50KA is a fault level of the breaker

Answer / shakeel ahmed

50KA is the breaking capacity. which means that for all fault currents below 50KA, the circuit breaker can de-energize the circuit successfully. if the fault current comes more than 50KA then this circuit breaker will not be able to break, but itself will get damaged.
