KA is the breaking capacity of short circuit current. It is
depends on standerd voltage valve

Answer / abhi26t

Foe a 50 KA MCCB, what is the duration of SC it can with stand.
Generally, electrical equipment is designed for 1 sec but is it true for MCCB also.

or its fault withstand time is 0.2 sec because with in this time frame it will trip.

Answer / amaresh patil

50KA means breaking Capacity of the Circuit Breakers

Answer / s.arunkumar

As per the standards for different voltage level there is
different short circuit fault value.
For ex: 11kV is 31.5kA and for 430V is 50kA.
ie., the breaker can withstand the short circuit of 50kA.

Answer / mohamed ali

50 KA is Instantaneous Current.

Answer / jaideep

i think 50ka is the rms value....

i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
