within 50 milliseconds … 5 seconds,
with an over-current between
The function is activated when
• an over-current measured at an output is greater than the corresponding
threshold for the set nominal current (Threshold 1).
• the measured over-current is present for more than 0.1 ms.
The activated circuit breaker can respond in one of three ways:
1. An over-current is present that is greater than Threshold 3
2. An over-current is present that is greater than Threshold 1,
but less than Threshold 2
3. An over-current is present that is greater than the nominal current, but less
than Threshold 1
