PURPOSE:To make the size small, by assembling a blocking filter to a circuit breaker used for power line carrier communication. CONSTITUTION:Components other than a coil L of a blocking filter are contained in an electric circuit component-containing section 13 in a molded circuit breaker S, and the coil L is wound on the iron core from a conductor 11 and it is connected to loads AO, WO, BO. By assembling the blocking filter to the circuit breaker S, the effect of a service entrance switch and a carrier high-frequency signal are prevented from being leaked externally through commercial power supply leads functionally. |
