Curves apply from -30°C to +60°C ambient temperature. Notes: 1. There is a memory effect that can act to shorten the long-time delay. The memory effect comes into play if a current above the long-time delay pickup value exists for a time and then is cleared by the tripping of a downstream device or the circuit breaker itself. A subsequent overload will cause the circuit breaker to trip in a shorter time than normal. The amount of time delay reduction is inverse to the amount of time that has elapsed since the previous overload. Approximately 20 minutes is required between overloads to completely reset memory. 2. Total clearing times shown include the response times of the trip unit, the circuit breaker opening, and the extinction of the current. 90 100 80 60 70 .005 50 .006 .005 40 .007 .006 20 .007 15 .01 .009 .008 8 .01 .009 .008 9 10 .015 6 .015 7 .02 5 .02 4 .03 3 .03 2 .04 1.5 .04 .9 1 .05 .8 .06 .05 .7 .07 .06 .5 Long-Time Pickup and Delay Instantaneous Pickup and Delay 2x – 10x .1 .09 .08 .07 .6 CHARACTERISTIC TRIP CURVE NO. 613-14 1.5 Instantaneous Pickup x In 30 TIME IN SECONDS 10000 9000 8000 80 50 60 40 30 20 15 8 9 10 6 7 5 4 3 2 1.5 .9 1 .8 .7 .5 .6 MULTIPLES OF SENSOR RATING (In) MULTIPLES OF SENSOR RATING (In) Curve No. 0613TC0114 Drawing No.B48095-613-14 Schneider Electric Brands
