2.6 Electronic overload shutdown and reset

2.6 Electronic overload shutdown and reset
An overload is permitted for a defined period of time for each selectivity module output. The
output is electronically shut down according to the "Shutdown characteristic" diagram after
the limit value has been exceeded.
Figure 2-6
The following applies for the SEL1200: In the range > 150 %, a higher current is briefly
permitted; afterwards it is shut down corresponding to the "Shutdown characteristic"
diagram.
The following applies for the SEL1400: In the range > 150 % of the selected current
response threshold, the current is limited to 150 %, typically after 10 ms to 100 ms, the
output is electronically shut down (LED of the output is lit red).
● An output current is continuously permissible up to the selected current response
threshold (LED of the output is lit green).
● In the range 100 - 150 % of the selected current response threshold, an overload current
is permissible for 5 seconds (LED of the output flashes green), then the output is
electronically shut down (LED of the output is lit red).
