WebbThe kA rating of a circuit breaker is a very important safety aspect to consider when designing a circuit. Without it, there is a good chance that a serious accident will occur. … Webbbreakers rated at varying levels of interrupting rating, from 42 kAIC to 100 kAIC at 600V and up to 200 kAIC at 480V. The interrupting ratings shown are rms symmetrical … Webb27 aug. 2015 · That formula is as follows: M = ((1)/(1+f) So to continue the example the formula would be: M = ((1)/(1+1.85) M = .351 So the final formula to actually find the short circuit rating on the secondary would be as follows: ISCA(sec) =ISCA(pri)* M * (Vpri/Vsec)Finally we get the following : ISCA(sec) =20,000* .351* (480/208) = 16,200 how much thc is in broad spectrum cbd
