PROBLEM TO BE SOLVED: To provide a two-pole circuit breaker by which an output signal lead wire of a CT of a circuit breaker is easily led, and that can be reliably fixed at a predetermined position.SOLUTION: A two-pole circuit breaker comprises: a current transformer (CT) mounted to a main circuit conductor; a CT output signal lead wire transmitting output signals of the CT to the outside of a unit body; an inter-pole insulation wall insulating the main circuit conductor from a conductor with the other polarity; and a unit body provided with a CT output signal lead wire drawing port. A CT output signal lead wire tucking-up section for winding and holding the CT output signal lead wire is integrally formed on the inter-pole insulation wall. |
