MCCB 400 Amps 50KA 430Volt AC
What is mean by 50KA
Answer Posted / 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.
Is This Answer Correct ? | 10 Yes | 11 No |

When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
