MCCB 400 Amps 50KA 430Volt AC What is mean by 50KA..

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.

MCCB 400 Amps 50KA 430Volt AC What is mean by 50KA..

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 / 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

MCCB 400 Amps 50KA 430Volt AC What is mean by 50KA..

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.

This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
