第1項記載の多極回路しや断器。[Claims for Utility Model Registration] (1) A contact arm that has a movable contact and is operated by an operating handle, a lever that is activated in the event of an overcurrent, and a lever that is suspended between this lever and the contact arm and that is operated by an operating handle. A plurality of single-pole circuit breakers each having an opening/closing spring that snaps the contact arm to the open/close position when the handle is operated and snaps the contact arm to the open position when the lever is operated; In multi-pole circuit breakers in which operating handles are connected to each other, the movable contact of the neutral pole circuit breakers connected to the neutral wire is the movable contact of the voltage pole circuit breakers connected to the voltage line. The attachment position of the opening/closing spring to the lever in the neutral pole circuit/disconnector is different from the attachment position of the opening/closing spring to the lever in the voltage circuit/disconnector so that the movable contact enters earlier and disconnects later than the movable contact. A multi-pole circuit disconnector characterized by: (2) The multi-pole circuit breaker according to claim 1, wherein the lever is provided with two mounting holes at different positions for mounting opening/closing springs.
