A compact electronic circuit breaker is simple to assemble. The circuit breaker has an insulating housing, a switch contact for reversibly contacting a load power circuit to be monitored, a triggering magnet acting by way of a triggering mechanism on the switch contact, and triggering electronics for actuating the triggering magnet. The switch contact, the triggering magnet, and the triggering electronics are fixedly mounted on a printed circuit board and they form a preassembled component together with the printed circuit board. The preassembled component can thereby be inserted in the housing as a unit.
