Series G J-Frame Circuit Breakers

Catalog types: JGE, JGS, and JGH circuit breakers, two, three- and four-pole .

notes:

1 . Curve accuracy applies from –20°C to +55°C ambient . For possible continuous ampere derating for ambient above 40°C, refer to Eaton . Temperatures above +85°C cause an over-temperature protection trip .

2 . Application frequency is 50/60 Hertz .

3 . There is a memory effect that can act to shorten the long delay . The memory effect comes into play if a current above the long 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 shorter time than normal . The amount of time reduction is inverse to the amount of time that has elapsed since the previous overload . Approximately five minutes is required between overloads to completely reset the memory .

4 . The right portion of the curve is determined by the interrupting rating of the circuit breaker .

5 . The left portion of the curve is shown as a multiple of the Long Delay Setting . (Long Delay Pickup = 115% of Ir) . Range is 110%–120% .

6 . Total clearing times shown include the response times of the trip unit, the breaker opening, and the interruption of the current .

7 . The Short Delay Pick Up has 9 settings/positions, 2–8 and 10, 12 .

8 . For high fault current levels, an additional fixed instantaneous hardware override (Ii) is provided at 14x . Instantaneous tolerance is ±20% .
