Circuit Breaker Time/Current Curves (Phase Current)

Magnum Power Circuit Breakers

Response: Long Delay & Short Delay Trip (FLAT & I2_T)

This curve is for 50Hz or 60Hz applications.

Notes:

1. 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 pick up 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 delay 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 memory.

2. The end of the curve is determined by the interrupting rating of the circuit breaker. 3. For the ground fault time/current curve see curve 70C1008. For the Instantaneous see

curve 70C1007.

4. The Long Delay Pickup Point (indicated by rapid flashing of Unit Status LED on the product) occurs at 110%, with a ± 5% tolerance. The Instantaneous settings have conventional 100% ±10% at the pick up points.

5. With zone interlocking on Short Delay utilized and no restraining signal, the minimum time band applies regardless of the setting.

6. This curve is shown as a multiple of the Long Delay Setting.

7. Breakpoint back to FLAT response indicated by dots occurs @8x I_r for upper line of I2_{T curve.}

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

1. 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 pick up value exists for a time and then is cleared by the tripping of a down stream 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 delay 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 memory.

2. The end of the curve is determined by the interrupting rating of the circuit breaker.

3. For the ground fault time/current curve see curve 70C1008. 4. This curve is shown as a multiple of the Rating Plug ( I_n). 5. The Instantaneous settings have conventional 100% ± 10% as the pickup points.

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

The memory effect comes into play if a current above the LONG PU 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 five minutes is required between overloads to completely reset memory.

2. This curve shown as a multiple of the LONG PU Setting (I_r). The actual Pickup point (indicated by rapid flashing of Unit Status LED on the product) occurs at 110% of the I_r, current, with a ±5% tolerance.

LongTIME Curve Equation: Trip = LongTIME *36/ I2_{, where I is a multiple of I} r.

The SHORT TIME function and the LongTIME function act independently and the entire set of LongTIME curves continue to be active even after the curves intersect. 3. With zone interlocking on Short Delay utilized and no restraining signal, the minimum SHORT

TIME band (0.10s) applies regardless of the SHORT TIME setting. 4. SHORT PU (Max M1 setting) is a additional setting, based on I_n (Plug), that can extend out where the SHORT PU will function.

Standard Breaker: Double Wide Breaker: 200A through 1250A M1=14x I_n 2000A, 2500A M1=14x I_n 1600A, 2000A, 2500A M1=12x I_n 3200A, 4000A, 5000A M1=12x I_n 3000A, 3200A . M1=10x I_n6300A M1=10x I_n 5. The SHORT PU points have 100% ± 5% tolerance.

6. SHORT SLOPE: FLAT

Tolerance is +0/ -80 ms for all settings except 0.10s setting is 0.06 to 0.13 0.20s setting is 0.15 to 0.22 7. SHORT SLOPE: I2_T

I2_{T slope flattens out at 8 x I}

r for top of band with FLAT time minimum value

prevailing for bottom of band.

Curve Trip Equation: Trip = SHORT TIME * 64/ I2_{, where I is a multiple of I} r (top)

Curve Trip Equation: Trip = SHORT TIME * 64/ I2 _{* 0.70 (bottom)}

The above equations indicate tolerance is +0/ -30% for all settings except 0.10s is +30%-25%

0.20s is +10%-25%

For all curves the lower flat response time value projected to I2_{T line will}

determine the other Break Point and shape of the curve.

8. The end of the curve is determined by the interrupting rating of the circuit breaker. 9. Curve applies from -20∞C to +55∞C ambient. Temperatures above +85∞C cause automatic trip. Breaker must be applied according to “Continuous Rating at Different Ambient” table.

Magnum and Magnum DS Circuit Breakers Response: Long Delay (I4_{T) & Short Delay Trip}

Notes:

1. There is a Long MEMORY (if enabled) effect that can act to shorten the Long Delay. The memory effect comes into play if a current above the LONG PU 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 delay 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 memory.

2. This curve is shown as a multiple of LONG PU Setting (Ir).

The actual Pickup point occurs at 110% of the I_r, current, with a ±5% tolerance.

LongTIME Curve Equation: Trip = LongTIME *1296/I4_{,where I is a multiple of I} r.

3. In this time region £ 0.5 seconds the I4 _{T Long TIME function will flatten out}

and be no faster than the Short TIME setting. This is to avoid a notch in graph. 4. SHORT PU (Max M1 setting) is an additional setting.

Circuit Breaker Time/Current Curves (Phase Current)

Magnum and Magnum DS Circuit Breakers Response: Instantaneous Trip This curve is for 50Hz or 60Hz applications.

Notes:

1. 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 delay 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 memory. 2. The end of the curve is determined by the interrupting rating of the circuit breaker.

3. This curve is shown as a multiple of the Rating Plug (I_n). 4. The Instantaneous settings have conventional 100% ± 10% as their pick up points.

5. Total clearing times shown include the response times of the trip unit, the breaker opening and the interruption of the current. 6. Additional settings of OFF and M1 are also available with Standard Frame: Double Wide Frame: 200A through 1250A M1=14x I_n 2000A, 2500A M1=14x I_n

7. For breakers rated 3200A and less having a 100kA rms interruption rating, an additional High Instantaneous Trip Module is provided in the breaker set to trip at a 170kA ± 10% instantaneous peak current level. This protection is functional even when the Instantaneous is set to the OFF position. .5 .6 .7 .8 .9 1 2 3 4 5 6 7 8 9 10 20 03 40 50 60 70 80 90 ₁₀₀ 2 0 3 0 4 0 5 0 8 0 7 0 6 0 9 0 100
