The time-current curve information is
to be used for application and
coordination purposes only.
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.
