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.
