Abstract

The circuit breaker consists of a housing and contact apparatus (17) arranged with terminals, a fault current releasing device (15), a summation current converter (10), an electronic circuit (19) dependent of network voltage, and an energy storage circuit (13) independent of network voltage. For greater simplicity in assembling and manufacture, the device has only one summation current converter (10) and one fault current releasing device (15), which are used not only for release by the circuit dependent of the network voltage, but also by the circuit independent of the network voltage.
