WebThere are three classes of duty cycle to consider: A HIGH duty cycle application is seam welding. For HIGH DUTY CYCLE applications, the circuit breaker size should be: CIRCUIT BREAKER SIZE (amps) = TRANSFORMER NAMEPLATE KVA x 2 A MEDIUM duty cycle application is defined as 7 spot welds or more in any 30-second time interval. This … WebAug 1, 2012 · First-cycle duty of fused low-voltage power circuit breaker = MF × first-cycle symmetrical RMS current. MF = 1.0 is applicable whenever the first-cycle short circuit X/R ratio at the fault point (i.e., source side of breaker) is 4.9 or less. If the first-cycle short circuit X/R ratio is greater than 4.9, the following formula from IEEE Std C37 ...
