Abstract

PURPOSE: To prevent an error operation of ripple generated in a control unit by providing a penetration type current transformer to detect the control current for tripping at the tripping coil side from the connection of a trip circuit and a sealing-in circuit.
CONSTITUTION: A penetrating type current transformer 5b to be a control current detecting device is provided at a tripping coil 46 side from the connection 21 of a trip circuit 9 and a sealing-in circuit 20. Therefore, at the former phase the breaking instruction of a breaker is input to an input terminal 9, the current I0 flowing from the sealing-in circuit 20 flows in to the next phase regardless of the penetration type current transformer 5b. As a result, the penetration type current transformer 5b does not detect the current I0 of the sealing-in circuit 20, but detects only the regular tripping instruation current I. The control signal can be detected with no error measurement, consequently.
