Electronic circuit breaker with thermomagnetic characteristic PM-0748-400-0 Advantages Adjustable tripping current for each output channel via current selector switch accessible from the front Ability to turn-on high load capacitance at each channel Sequential and load-dependent switching-on of channels Comprehensive single-channel-diagnostics and remote switching on/off of each output channel via 2-wire-interface LED signalization and remote request for each output channel Group alarm contact for simple diagnosis Applications ECONOMY SMART 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 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.
