The time-current curve information is to be used
for application and coordination purposes only.
Curves apply from -30° to +60°C ambient
temperature.
Notes:
1. The end of the curve is determined by the
interrupting rating of the circuit breaker.
2. Total clearing times shown include the
response times of the trip unit, the circuit
breaker opening, and the extinction of the
current.
3. The instantaneous region of the trip curve
shows maximum total clearing times. Actual
clearing times in this region can vary
depending on the circuit breaker mechanism
design and other factors. The actual clearing
time can be considerably faster than indicated.
Contact your local Sales Office for additional
information.
4. For a withstand circuit breaker, instantaneous
can be turned OFF. See 613-7 for
instantaneous trip curve. See 613-10 for
instantaneous override values.
5. See 613-4 and 613-5 for long-time pickup,
long-time delay, short-time pickup, and short-
time delay trip curves.
