Smart circuit breaker


General DPN

E-T-A Circuit Breakers has introduced the E-l 048-800 smart circuit breaker. Designed with solid state technology to provide relay control, the unit is said to be the first device of its kind to combine solid-state switching, electronic circuit protection, analog signal output and diagnostic functions.

The unitís power controller is suitable for switching dc loads in automotive and automation applications, and for low voltage dc or multiplex control systems used in power circuits on boats and other vehicles. The 0 to 5 V analog output is proportional to the current flowing through the device. If this output is connected to a PLC or ASIC microcontroller, the signal can be used to provide intelligent relay control.
