    pl15152231-3_pole_ac_electrical_contactor_690v_1000v_magnetic_contactor_switch_9a_620a.jpg Is it really a controversy?
    See the picture above.
    If you were handed an electrical drawing for a control box that you had to supply the line and load of the object in the picture above and the line side was for a single phase motor. Would you consider it a problem if you were required to use the device in question to disconnect both the hot and neutral?

    As an inspector, would you question the switching of the neutral?

    Now this might have been a trick question. You know, I'm not an electrician.

    Any other takers? No commercial electrical guys here?

    Actually, there are some pretty neat residential control systems that could have this same setup.

    I would need the manufacture directions of the breaker to know if it is allowed for this device.

    It is a tengen breaker may be an x-2 type. I most often see these for motor controls.
