1.Calculation formula = power/voltage *3 (impact current) 2.For example: 3000W equipment 380V voltage select circuit breaker, 3000W*3 (impulse current) /380V≈ 23.68A ≈25A, we choose 25A circuit breaker or leakage circuit breaker

It would be convenient to use a tool to calculate the capacitor charging time of an RC circuit, but you may also use the formula: t = R × C where: t - Capacitor charge time; R - Resistance of the resistor; and C - Capacitance of the capacitor. It means you may determine the cha...
breaks. Hence, time t isbreakingtime of thecircuit breaker. As this time is very less in scale of mili second, it is assumed that all the heat produced during fault is absorbed by theconductorsince there is no sufficient time for convention and radiation of heat. ...
Shock absorber for circuit breaker If you are not sure about the product you need, you may use the “calculating formula” to look up the products you need. Calculation DLC Series Shock absorber for circuit breaker DLD Series Shock absorber for circuit breaker...
In addition, a typical short-circuit calculation would have accuracy of 5 percent if not worse (due to the limited accuracy of models and parameters). As a result, breaker practitioners apply hefty margins in breaker ratings. It is not uncommon to have a 20-percent margin in the asymmetrical...
