摘要：A conductor (34) is clamped/fixed to a terminal portion (33) of the circuitbreaker main body (1) by clamping members (35). A current-supply information

measuring unit (30) including a Hall element (38) for detecting magnetic fluxes generatedby a current flowing through the conductor (34) and converting them into an electricsignal, contact jigs (41) for detecting a phase voltage by contacting to the conductor (34),an electronic circuit portion (43) for processing a voltage signal detected by the contactjigs (41) and the electric signal of the Hall element (38), and an outputting means (40) foroutputting a processed result is detachably attached to a terminal portion (33) of thecircuit breaker main body (1). Accordingly, the circuit breaker in which an instrumentcurrent transformer (18) is not built can display current-supply information which aresupplied to a load protected by the circuit breaker main body (1).
