Applications
The BASIC SMART circuit breakers guarantee maximum system availability.
In the event of overload, only the faulty current paths are reliably switched
off without affecting the remaining circuits thanks to active current limiting
to 1.7 times the rated current. The electronic circuit breaker distributes and
monitors the load current over several current circuits. Overloads and short
circuits on an output are reliably recognized. The electronics permit brief
current peaks and switch longer overloads off. The rated current for each
output can be individually set with a current selector switch accessible from the
front. The outputs are activated depending on the time delay and load to avoid
an overload current. If the rated current is exceeded for a certain amount of
time, the output will be switched off automatically and can be reactivated after
a waiting time (thermal relaxation) using the pushbutton or the remote signal
input S1. The pushbutton can also be used to switch the output manually. It is
possible to read out the state of each output using the three signal contacts.
The state of each output is also indicated with a multi-colored LED.
