WebNov 28, 2007 · Nov 27, 2007. #5. AIC ratings for relays. In my experience, a typical application is a 20 Amp rated relay that usually divides branches of a circuit from a 20 Amp breaker to lighting loads so that they can be controlled by a time clock or individual switches or by a photocell. Some manufacturers show a 10,000 AIC rating and some show a 5000 … WebJan 22, 2011 · We need to know the Cutler hammer LV motor contractor relay Interrupting rating and drop out time Details are as under : 1.

For an 800 A SJ, it is 13,200 A. ... find a tested combination where that 5kA rated contactor is good for maybe 50kA with a specific breaker and overload relay. The fault current ratings are actually fairly complex.
WebJan 13, 2024 · The concept correlates with the requirements of NEC 240.86(A), which do not allow the use of fuse let-through (engineered method) to show protection of circuit breakers at fault currents higher than the circuit breaker marked interrupting rating unless the circuit breaker is passive (does not unlatch in the first half cycle). WebInterrupting ratings are determined by testing the instantaneous-trip circuit breakers in combination with a contactor and overload relay. Select instantaneous-trip circuit breakers as follows: This selection table is suitable for motors, other than NEMA Design E, with locked-rotor indicating code letters per NEC ® Table 430.7 (b) as follows:
WebFor example, a GE AM-13.8-500 air blast breaker has a momentary and interrupting duty rating of 19.56/37 kA at 13.8 kV. SmartDuty™ provides a warning flag if the current exceeds 17.6/33.3 kA in either the momentary or interrupting rating. If the current exceeds 19.56/37 kA, a violation is flagged.
