Applications

ECONOMY REMOTE circuit breakers with a thermomagnetic characteristic
represent an economical alternative to the classic circuit breaker. They also
ensure reliable tripping even in the case of high line resistance. This makes the
circuit breakers ideal for use in standard machine production. 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
tripping current for each output can be individually set in 6 steps only with a
higher-level control system (e.g. PLC). 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.
